The Common Anatomy Reference Ontology (CARO) is being developed to facilitate interoperability between existing anatomy ontologies for different species, and will provide a template for building new anatomy ontologies. Common Anatomy Reference Ontology Based on CARO 1.0, with modifications and additions by David Osumi-Sutherland, Chris Mungall, Ramona Walls and Melissa Haendel. 2023-03-15 IAO:0000112 uberon example_of_usage true example_of_usage example of usage definition IAO:0000116 uberon editor_note true editor_note editor note expand expression to term replaced by If R <- P o Q is a defining property chain axiom, then it also holds that R -> P o Q.

Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point. An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other. is preceded by preceded_by http://www.obofoundry.org/ro/#OBO_REL:preceded_by BFO:0000062 external uberon preceded_by preceded_by preceded by preceded by precedes x precedes y if and only if the time point at which x ends is before or equivalent to the time point at which y starts.

This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing. characteristic of bearer of this apple is bearer of this red color this vase is bearer of this fragility Inverse of characteristic_of A bearer can have many dependents, and its dependents can exist for different periods of time, but none of its dependents can exist when the bearer does not exist. bearer_of is bearer of RO:0000053 external bearer_of bearer_of bearer of has characteristic participates in this blood clot participates in this blood coagulation this input material (or this output material) participates in this process this investigator participates in this investigation a relation between a continuant and a process, in which the continuant is somehow involved in the process participates_in RO:0000056 external uberon participates_in participates_in participates in participates in has participant this blood coagulation has participant this blood clot this investigation has participant this investigator this process has participant this input material (or this output material) a relation between a process and a continuant, in which the continuant is somehow involved in the process Has_participant is a primitive instance-level relation between a process, a continuant, and a time at which the continuant participates in some way in the process.

This branch of the ontology deals with causal relations between entities. It is divided into two branches: causal relations between occurrents/processes, and causal relations between material entities. We take an 'activity flow-centric approach', with the former as primary, and define causal relations between material entities in terms of causal relations between occurrents. To define causal relations in an activity-flow type network, we make use of 3 primitives: * Temporal: how do the intervals of the two occurrents relate? * Is the causal relation regulatory? * Is the influence positive or negative? The first of these can be formalized in terms of the Allen Interval Algebra. Informally, the 3 bins we care about are 'direct', 'indirect' or overlapping. Note that all causal relations should be classified under a RO temporal relation (see the branch under 'temporally related to'). Note that all causal relations are temporal, but not all temporal relations are causal. Two occurrents can be related in time without being causally connected. We take causal influence to be primitive, elucidated as being such that has the upstream changed, some qualities of the donwstream would necessarily be modified. For the second, we consider a relationship to be regulatory if the system in which the activities occur is capable of altering the relationship to achieve some objective. This could include changing the rate of production of a molecule. For the third, we consider the effect of the upstream process on the output(s) of the downstream process. If the level of output is increased, or the rate of production of the output is increased, then the direction is increased. Direction can be positive, negative or neutral or capable of either direction. Two positives in succession yield a positive, two negatives in succession yield a positive, otherwise the default assumption is that the net effect is canceled and the influence is neutral. Each of these 3 primitives can be composed to yield a cross-product of different relation types. Do not use this relation directly. It is intended as a grouping for a diverse set of relations, all involving cause and effect. causally related to relation that links two events, processes, states, or objects such that one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly or wholly responsible for the effect, and the effect is partly or wholly dependent on the cause. https://en.wikipedia.org/wiki/Causality p is causally upstream of q iff p is causally related to q, the end of p precedes the end of q, and p is not an occurrent part of q.

A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players. Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process.

(axiom label in BFO2 Reference: [083-003]) BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay.

A portion of matter is anything that includes elementary particles among its proper or improper parts: quarks and leptons, including electrons, as the smallest particles thus far discovered; baryons (including protons and neutrons) at a higher level of granularity; atoms and molecules at still higher levels, forming the cells, organs, organisms and other material entities studied by biologists, the portions of rock studied by geologists, the fossils studied by paleontologists, and so on.Material entities are three-dimensional entities (entities extended in three spatial dimensions), as contrasted with the processes in which they participate, which are four-dimensional entities (entities extended also along the dimension of time).According to the FMA, material entities may have immaterial entities as parts – including the entities identified below as sites; for example the interior (or ‘lumen’) of your small intestine is a part of your body. BFO 2.0 embodies a decision to follow the FMA here. A material entity is an independent continuant that has some portion of matter as proper or improper continuant part. (axiom label in BFO2 Reference: [019-002]) Every entity which has a material entity as continuant part is a material entity. (axiom label in BFO2 Reference: [020-002]) every entity of which a material entity is continuant part is also a material entity. (axiom label in BFO2 Reference: [021-002]) (forall (x) (if (MaterialEntity x) (IndependentContinuant x))) // axiom label in BFO2 CLIF: [019-002] (forall (x) (if (and (Entity x) (exists (y t) (and (MaterialEntity y) (continuantPartOfAt x y t)))) (MaterialEntity x))) // axiom label in BFO2 CLIF: [021-002] (forall (x) (if (and (Entity x) (exists (y t) (and (MaterialEntity y) (continuantPartOfAt y x t)))) (MaterialEntity x))) // axiom label in BFO2 CLIF: [020-002] material entity A material entity is an independent continuant that has some portion of matter as proper or improper continuant part. (axiom label in BFO2 Reference: [019-002]) Every entity which has a material entity as continuant part is a material entity. (axiom label in BFO2 Reference: [020-002]) every entity of which a material entity is continuant part is also a material entity.

Or, a substance produced by a cellular organism with granularity above the level of a protein complex. CARO:0000000 Following BFO, material anatomical entities may have immaterial parts (the lumen of your stomach is part of your stomach). The granularity limit follows the limits set by the Gene Ontology on the granularity limit for GO:cellular_component. Note that substances produced by an organism (sweat, feaces, urine) do not need to be part of an organism to qualify as an anatomical structure. anatomical entity A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. CAROC:Brownsville2014 Material anatomical entity that is a single connected structure with inherent 3D shape generated by coordinated expression of the organism's own genome. CARO:0000003 Note that the definition does not say 'generated exclusively by the co-ordinated expression of the organism's own genome', so this is still valid for cases where normal morphogenesis requires the actions of a facultative symbiont, or some looser dependency such as the a requirement for the presence of gut flora for normal gut development. connected anatomical structure Examples include feces, urine, blood, blood plasma, lymph, hemolymph, cerbro-spinal fluid. This class does not encompass anatomical entities with inherent 3D structure such as dentine and arthropod cuticle. Material anatomical entity in a gaseous, liquid, semisolid or solid state; produced by anatomical structures or derived from inhaled and ingested substances that have been modified by anatomical structures as they pass through the body and that does not have inherent 3D shape generated by coordinated expression of the organism's own genome. portion of organism substance CARO:0000004 Note - CARO explicitly declares organisms substances to be part of (some) organism. organism substance An Immaterial anatomical entity of three dimensions, that is generated by morphogenetic or other physiologic processes and that is bounded by an anatomical surface. CARO:0000005 Original definition: "Non-material anatomical entity of three dimensions, that is generated by morphogenetic or other physiologic processes; is surrounded by one or more anatomical structures; contains one or more organism substances or anatomical structures." The last clause. "contains one or more organism substances or anatomical structures" was dropped from the definition because it was an unnecessary restriction. anatomical space An anatomical entity that has mass. CARO:0000006 material anatomical entity Anatomical entity that has no mass. CARO:0000007 immaterial anatomical entity A line between two points where these are typically used to measure some aspect of morphology, such as the distance between the eyes or the length of a leg. A one dimensional, immaterial anatomical entity. CARO:0000008 anatomical line The tip of the nose or other material anatomical entity, or the end of an anatomical line. Non-material anatomical entity of zero dimension, which forms a boundary of an anatomical line or surface. CARO:0000009 anatomical point A non-material anatomical entity of two dimensions. Anatomical boundaries are contiguous structures. Except in the case of abstracted fiat boundaries such as the midline plane of an organism, all 2D anatomical entities have a 3 dimensional projection. For example, the surface of the shell of a muscle has a distinct shape that projects into the third dimension. Note that boundaries are 2D structures. They have no thickness - and so can not be sites of gene expression or gene product localisation. For this, use boundary region terms. anatomical boundary Multicellular, connected anatomical structure that has multiple organs as parts and whose parts work together to achieve some shared function. CARO:0000011 connected anatomical system Anatomical structure that is an individual member of a clade and, at some point in its life-cycle, consists of more than one cell. CARO:0000012 MH: Can't define this class based on 2 or more cells because most multi cellular organisms (if not all) have only a single cell at some point in life history. MH: sexual subtypes should probably be logically defined based on sexual processes or sex qualities. multicellular organism An anatomical structure that has as its parts a maximally connected cell compartment surrounded by a plasma membrane. CL:0000000 GO:0005623 CARO:0000013 deprecate and replace with CL or GO term? cell Anatomical structure that is part of a cell and that has a granularity level equal to that of a protein complex or higher. cell component CARO:0000014 This is declared equivalent with GO:0044464. The definition should be co-ordinated with GO. We could obsolete the CARO class and just use the GO class. cell part Multi-tissue structure that is part of a compound organ. CARO:0000019 compound organ component 1 An organ that consists of a single multi-tissue structure. CARO:0000021 simple organ 2 An organ consisting of multiple, distinct multi-tissue structures. CARO:0000024 compound organ Gonochoristic organism that can produce male gametes. CARO:0000027 male organism Gonochoristic organism that can produce female gametes. CARO:0000028 female organism Multi-cellular organism that can produce both male and female gametes. dioecious organism CARO:0000029 hermaphroditic organism dioecious organism RELATED Multi-cellular organism that does not produce gametes. CARO:0000030 asexual multi-cellular organism Anatomical structure which is a subdivision of a whole organism, consisting of components of multiple anatomical systems, largely surrounded by a contiguous region of integument. Old definition: Anatomical structure which is a primary subdivision of whole organism. The mereological sum of these is the whole organism. CARO:0000032 organism subdivision 0 0 An anatomical structure that has no cells or cell parts as a part. CARO:0000040 Example. Insect cuticle, eggshell, hair. acellular anatomical structure Anatomical group that has its parts adjacent to one another. CARO:0000041 anatomical cluster true Anatomical group that has its parts adjacent to one another. FMA:49443 A multicellular anatomical structure that is associated with an embryo and derived from the zygote from which it develops, but which does not contribute to the embryo proper or to structures that are part of the same organism after embryogenesis. CARO:0000042 MH: define as not part of embryo, or will not develop into embryo? MH: changed def to exclude cells so this class could be included in gross anatomical part. DOS: Changed to something that I think works for both vertebrates and invertebrates and that keeps the restriction to multicellular structures. Old def: "Anatomical structure that is contiguous with the embryo and is comprised of portions of tissue that will not contribute to the embryo.". One remaining question - perhaps zygote is too restrictive given that some organisms have parthenogenesis e.g. aphids? extraembryonic structure Multicellular anatomical structure that consists of many cells of one or a few types, arranged in an extracellular matrix such that their long-range organisation is at least partly a repetition of their short-range organisation. relabel 'tissue'? portion of tissue CARO:0000043 tissue Hermaphroditic organism that produces gametes first of one sex, and then later of the other sex. consecutive hermaphroditic organism CARO:0000045 sequential hermaphroditic organism consecutive hermaphroditic organism RELATED Hermaphroditic organism that produces both male and female gametes at the same time. serially hermaphroditic organism CARO:0000046 synchronous hermaphroditic organism serially hermaphroditic organism RELATED Multi-cellular organism that has male and female sexes. monoecious organism CARO:0000048 gonochoristic organism monoecious organism RELATED Sequential hermaphroditic organism that produces\ngametes first of the male sex, and then later of the\nfemale sex. CARO:0000049 protandrous hermaphroditic organism Sequential hermaphroditic organism that produces\ngametes first of the female sex, and then later of the\nmale sex. CARO:0000050 protogynous hermaphroditic organism Anatomical structure consisting of at least two non-overlapping organs, multi-tissue aggregates or portion of tissues or cells of different types that does not constitute an organism, organ, multi-tissue aggregate, or portion of tissue. CARO:0000054 Obsoleted because the definition is too opaque. Also because this class was a subclass of 'anatomical structure' (CARO_0000003), but a similarly named class in the refactored caro (CARO_0020000) is a sibling of 'anatomical structure'. anatomical group true Anatomical structure consisting of at least two non-overlapping organs, multi-tissue aggregates or portion of tissues or cells of different types that does not constitute an organism, organ, multi-tissue aggregate, or portion of tissue. 2 Anatomical structure that has as its parts two or more portions of tissue of at least two different types and which through specific morphogenetic processes forms a single distinct structural unit demarcated by bona-fide boundaries from other distinct structural units of different types. CARO:0000055 multi-tissue structure Anatomical space that is part of a cell. CARO:0000062 cell space Portion of organism substance located within a cell. CARO:0000063 Deprecate this as better to leave it up to GO to define? portion of cell substance 1 Organism that consists of a single cell for all of its life-cycle. single-cell organism CARO:0000064 unicellular organism Acellular anatomical structure that consists of a thin sheet of fibrous proteins that underlie and support the cells of an epithelium. It separates the cells of an epithelium from any underlying tissue. CARO:0000065 basal lamina true Portion of tissue, that consists of one or more layers of epithelial cells connected to each other by cell junctions and which is underlain by a basal lamina. CARO:0000066 epithelium Unilaminar epithelium that consists of a single layer of cuboidal cells. CARO:0000067 simple cuboidal epithelium Unilaminar epithelium that consists of a single layer of columnar cells. CARO:0000068 simple columnar epithlium Epithelium that consists of more than one layer of epithelial cells. CARO:0000069 multilaminar epithelium Unilaminar epithelium that consists of a single layer of squamous cells. CARO:0000070 simple squamous epithelium Epithelium that consists of epithelial cells not arranged in one ore more layers. CARO:0000071 atypical epithelium Compound organ that contains one or more macroscopic anatomical spaces. CARO:0000072 cavitated compound organ Epithelium that consists of a single layer of epithelial cells. CARO:0000073 unilaminar epithelium Compound organ that does not contain macroscopic anatomical spaces. CARO:0000074 solid compound organ Cell which has as its part a cytoskeleton that allows for tight cell to cell contact and which has apical-basal cell polarity. CARO:0000077 epithelial cell true A fluid that is circulated around a multicellular organism carrying nutrients and carrying away waste products. Examples: blood, lymph, hemolymph circulating fluid An appendage that is one of a bilateral pair. paired appendage unpaired appendage 2 A structure consisting of multiple cell components but which is not itself a cell and does not have (complete) cells as a part. multi-cell-component structure CARO:0001000 Examples: a bundle of neuron projections in the brain; a region neuropil in an arthropod central nervous system; a region of cortex (preikaryal rind) in an arthropod brain. multi-cell-part structure A fasciculated bundle of neuron projections (GO:0043005), largely or completely lacking synapses. nerve fiber bundle CARO:0001001 neuron projection bundle nerve fiber bundle EXACT A two dimensional anatomical structure that is the boundary between an anatomical structure and an anatomical substance, an anatomical space or the organism's environment. Examples include the surface of your skin, the surface of the lining of your gut; the surface of the endothelium of you aorta that is in contact with blood. CARO:0000010 Old definition: "Non-material anatomical entity of two dimensions, that is demarcated by anatomical lines or points on the external or internal surfaces of anatomical structures." Note, in the new definition, the space referred to is not necessarily an anatomical space. It may be the outside of an organism. anatomical surface A two dimensional anatomical entity that does not correspond to any physical discontinuity. Fiat anatomical boundaries are generally defined using external physical criteria as landmarks. One might argue that all boundaries are actually fiat in the sense that there must be some fiat element at a fine enough scale of granularity. This ontology choses to ignore this issue as below the level of granularity relevant to anatomy. (DOS121102) fiat anatomical boundary An anatomical boundary that corresponds to some physical discontinuity. One might argue that all boundaries are actually fiat in the sense that there must be some fiat element at a fine enough scale of granularity. This ontology choses to ignore this issue as below the level of granularity relevant to anatomy. (DOS121102) bona-fide anatomical boundary A two dimensional anatomical entity that is the boundary of a domain of expression of some gene. gene expression boundary A two dimensional anatomical entity that is not a morphological boundary and that cells do not cross during development. developmental compartment boundary A two dimensional anatomical structure that corresponds to some structural discontinuity. morphological boundary Anatomical structure that is part of a multicellular organism and is at the gross anatomical level, e.g. above the level of a cell. Included are portions of organism substances such as blood, multi-cell-part structures such as axon tracts, acellular anatomical structures such as hair, and organism subdivisions such as head. Excluded is the whole organism and more granular parts of the organism, such as atoms, molecules, macromolecular complexes and cells. 10.7.2011 gross anatomical part Anatomical structure that surrounds an immaterial anatomical entity. 10.10.2011 See CARO tracker #6, but essentially Chamber has connotations of space, rather than wall: see http://en.wiktionary.org/wiki/chamber This term is extremely abstract as a genus - it specifies no granularity at all. It could refer to a chamber in a protein complex in a membrane as easily as some big multi-tissue structure like a segment of gut. obsolete anatomical chamber true Material anatomical entity that is a member of an individual species or is a viral or viroid particle. Melissa Haendel 9/18/11 organism or virus or viroid organism All anatomical planes are fiat anatomical boundaries - no morphological boundary could ever be a perfect plane. anatomical plane A fiber-shaped subdivision of a neuron projection along its long axis. neuron projection bundle segment A fiber-shaped subdivision of a neuron projection along its long axis. A subdivision of a neuron projection along its long axis that is as long as it is wide (and so does not qualify as fiber-shaped). This term was added in order to define fasciculation relations. It seems unlikely that it will be used directly in curation. neuron projection bundle subsegment A subdivision of a neuron projection along its long axis that is as long as it is wide (and so does not qualify as fiber-shaped). Epithelium of the integumentary system. epidermis Connected anatomical system that forms a barrier between an animal and its environment - generally consisting of an epidermis, which may be covered by some acellular structure. integumentary system An anatomical group whose members are arranged in a line. Examples include the rows of sense organs commonly found in the cuticles of insects. aligned anatomical group Anatomical group whose parts are close together, forming a cluster. Not to be confused with anatomical cluster, in the FMA sense. FMA anatomical structures are connected structures made up of heterologous parts. For example, joints are anatomical clusters in the FMA. The FMA definition on anatomical cluster, and the CARO1 definition that was based on it, are defined largely by exclusion. clustered anatomical group Anatomical group whose parts are close together, forming a cluster. One of a set of semi-repetitive organism subdivisions serially arranged along the anterior-posterior axis of an organism and excluding appendages if present. segment body A subdivision of an appendage along its proximal-distal axis, consisting consisting of components of multiple anatomical systems, largely surrounded by a contiguous region of integument. appendage subdivision Ceolom, cranial cavity, mammalian thoracic and abdominal body cavities, arthropod hemoceol. A major anatomical space of an organism in which major organs are located. obsolete body cavity true An anatomical structure consisting of multiple cells, organs, tissues, distributed throught an organism, that act together to perform some physiological function. Examples include connected systems such as the circulatory system - whose elements function together to perform the function or blood circulation - and disconected systems such as the immune system. anatomical system Examples include connected systems such as the circulatory system - whose elements function together to perform the function or blood circulation - and disconected systems such as the immune system. 2 An anatomical system consisting of multiple disconnected parts. Examples include the immune system and the endocrine system. disconnected anatomical system An anatomical system consisting of multiple disconnected parts. An anatomical structure that has more than one cell as a part. djs93 Sun Feb 27 10:53:00 GMT 2011 CARO:0010000 multicellular anatomical structure There is a cost to burying this in PATO. We lose that we could relax the cardinality assertion to subClassOf has_part some cell. I'm sure having this axiom inherited would come in handy. DOS A small cluster of cells of various types which form a discrete structure, largely delimited by a morphological boundary and whose components work together to make the whole structure capable of a specific function. djs93 Sun Feb 27 11:00:35 GMT 2011 CARO:0010001 Examples include arthropod sensilla. cell cluster organ 2 An anatomical structure consisting of multiple cell cluster organs, largely delimited by a morphological boundary and whose components work together to make the whole structure capable of a specific function. djs93 Sun Feb 27 11:13:17 GMT 2011 CARO:0010002 Examples: compound eye; Johnston's organ. compound cell cluster organ An organism subdivision that protrudes from the body. djs93 Fri Mar 04 07:09:17 GMT 2011 CARO:0010003 appendage An individual member of a clade of cellular organisms. 7.16.2011 CARO:0010004 A general term for organism that is agnostic about single cell vs multi-cellular. Note that this is a subclass of 'anatomical structure', meaning that an organism must be a connected structure. For example, if I take one plant and make a rooted cutting from a it, I now have two (clonally related) organisms. cellular organism One of a set of semi-repetitive organism subdivisions serially arranged along the anterior-posterior axis of an organism, including appendages if present. djs93 Fri Mar 04 07:13:46 GMT 2011 metamere CARO:0010005 segment One of a set of semi-repetitive organism subdivisions serially arranged along the anterior-posterior axis of an organism, including appendages if present. A subdivision of the organism along the anterior-posterior axis that consists of multiple adjacent segments that are either fused, and/or share more structure with each other than with segments in adjacent tagmata. djs93 Fri Mar 04 07:14:57 GMT 2011 CARO:0010006 tagma One of a set of semi-repetitive organism subdivisions serially arranged along the proximal-distal axis of an appendage djs93 Fri Mar 04 07:16:21 GMT 2011 CARO:0010007 appendage segment An epithelium that is rolled into a tube. djs93 Wed Mar 09 06:22:07 GMT 2011 CARO:0010009 epithelial tube djs93 Wed Mar 09 08:02:50 GMT 2011 CARO:0010010 epithelial sac 2 Material anatomical entity consisting of multiple anatomical structures that are not connected to each other. CARO:0000054 disconnected anatomical group A multicellular anatomical structure that has subparts of multiple organs as a part. anatomical cluster CARO:0000041 Examples include joints of the vertebrate musculoskeletal system (each has (fiat) parts of multiple bone organs as a part). multi organ part structure A cluster of cells, largely surrounded by a morphological boundary. cell cluster A cluster of cells, largely surrounded by a morphological boundary. An anatomical structure consisting of one or more cells. 2018-09-28T14:20:19Z cellular anatomical structure With a reflexive part_of relation this might safely be defined as 'anatomical structure' that has_part some cell A multicellular anatomical structure largely delimited by a morphological boundary whose components work together to make the whole structure capable of a specific function. organ 1 An single tissue, largely surrounded by a morpholigical boundary, whose cells work together to make the whole structure capable of a specific function. single tissue organ Entity that is, is part of, or derived from an organism, virus, or viroid or a collection of them.
