2012-04-05: Barry Smith The official OBI definition, explaining the meaning of a class or property: 'Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions' is terrible. Can you fix to something like: A statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property. Alan Ruttenberg Your proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can't be evaluated by those criteria. On the specifics of the proposed definition: We don't have definitions of 'meaning' or 'expression' or 'property'. For 'reference' in the intended sense I think we use the term 'denotation'. For 'expression', I think we you mean symbol, or identifier. For 'meaning' it differs for class and property. For class we want documentation that let's the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let's the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The 'intended reader' part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition. Personally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable. We also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.

The first embryonic hint of a metanephros is the formation of the metanephric duct that appears as a ureteric diverticulum arising at the base of preexisting mesonephric duct. The ureteric diverticulum grows dorsally into the posterior region of the nephric ridge. Here it enlarges and stimulates the growth of metanephric tubules that come to make up the metanephric kidney. The metanephros becomes the adult kidney of amniotes, and the metanephric duct is usually called the ureter.[well established][VHOG]

In zebrafish, No stomach, small intestine, or large intestine can be distinguished. However, differences can be found in the morphology of the mucosa columnar epithelial cells and the number of goblet cells, suggesting functional differentiation. The intestine has numerous folds that become progressively shorter in a rostral-to-caudal direction. Proportionally, these folds are significantly larger than the finger-like intestinal villi of mammals and other amniotes (Wallace et al. 2005). Columnar-shaped absorptive enterocytes are the most numerous in the zebrafish intestinal epithelium. Goblet cells are the second most populous epithelial cell type.

We restrict this to the vertebrate specific structure - see the grouping class 'food storage organ' for analogous structures in other species. Teleosts: Zebrafish is functionally stomach-less, but may retain ontogenic footprint. Although the precise shape and size of the stomach varies widely among different vertebrates, the relative positions of the oesophageal and duodenal openings remain relatively constant. As a result, the organ always curves somewhat to the left before curving back to meet the pyloric sphincter. However, lampreys, hagfishes, chimaeras, lungfishes, and some teleost fish have no stomach at all, with the oesophagus opening directly into the intestine. The gastric lining is usually divided into two regions, an anterior portion lined by fundic glands, and a posterior with pyloric glands. Cardiac glands are unique to mammals, and even then are absent in a number of species. The distributions of these glands vary between species, and do not always correspond with the same regions as in man. Furthermore, in many non-human mammals, a portion of the stomach anterior to the cardiac glands is lined with epithelium essentially identical to that of the oesophagus. Ruminants, in particular, have a complex stomach, the first three chambers of which are all lined with oesophageal mucosa
An expanded region of the vertebrate alimentary tract that serves as a food storage compartment and digestive organ. A stomach is lined, in whole or in part by a glandular epithelium.
Portion of alimentary canal with increased circular and longitudinal smooth muscle. Bounded posteriorly by the pyloric sphincter. Mucosal lining has increased folding.[AAO]
It appears that the stomach has an ancient origin. The stomach first appears in the fish lineage. The prevertebrate chordates do not have a true stomach, whereas the cartilaginous and bony fish do. Although most fish do have a true stomach, some fish species appear to have lost the stomach secondarily. The remaining vertebrate lineages do have a true stomach (at least in the adult animal), although there is great variation in the size and shape of the stomach.[well established][VHOG]

Ovaries of some kind are found in the female reproductive system of many animals that employ sexual reproduction, including invertebrates. However, they develop in a very different way in most invertebrates than they do in vertebrates, and are not truly homologous. Many of the features found in human ovaries are common to all vertebrates, including the presence of follicular cells, tunica albuginea, and so on. However, many species produce a far greater number of eggs during their lifetime than do humans, so that, in fish and amphibians, there may be hundreds, or even millions of fertile eggs present in the ovary at any given time. In these species, fresh eggs may be developing from the germinal epithelium throughout life. Corpora lutea are found only in mammals, and in some elasmobranch fish; in other species, the remnants of the follicle are quickly resorbed by the ovary. In birds, reptiles, and monotremes, the egg is relatively large, filling the follicle, and distorting the shape of the ovary at maturity. Amphibians and reptiles have no ovarian medulla; the central part of the ovary is a hollow, lymph-filled space. The ovary of teleosts is also often hollow, but in this case, the eggs are shed into the cavity, which opens into the oviduct. Although most normal female vertebrates have two ovaries, this is not the case in all species. In birds and platypuses, the right ovary never matures, so that only the left is functional. In some elasmobranchs, the reverse is true, with only the right ovary fully developing. In the primitive jawless fish, and some teleosts, there is only one ovary, formed by the fusion of the paired organs in the embryo
The female muscular organ of gestation in which the developing embryo or fetus is nourished until birth.
The hollow muscular organ in female mammals in which the blastocyst normally becomes embedded and in which the developing embryo and fetus is nourished. Its cavity opens into the vagina below and into a uterine tube on either side. [TFD][VHOG]
An infundibulum, uterine tube, uterus, and vagina also differentiate along the oviducts of eutherian mammals.[well established][VHOG]
Two uteruses usually form initially in a female fetus, and in placental mammals they may partially or completely fuse into a single uterus depending on the species. In many species with two uteruses, only one is functional. Humans and other higher primates such as chimpanzees, along with horses, usually have a single completely fused uterus, although in some individuals the uteruses may not have completely fused [Wikipedia:Uterus]
Most animals that lay eggs, such as birds and reptiles, have an oviduct instead of a uterus. In monotremes, mammals which lay eggs and include the platypus, either the term uterus or oviduct is used to describe the same organ, but the egg does not develop a placenta within the mother and thus does not receive further nourishment after formation and fertilization. Marsupials have two uteruses, each of which connect to a lateral vagina and which both use a third, middle 'vagina' which functions as the birth canal. Marsupial embryos form a choriovitelline 'placenta' (which can be thought of as something between a monotreme egg and a 'true' placenta), in which the egg's yolk sac supplies a large part of the embryo's nutrition but also attaches to the uterine wall and takes nutrients from the mother's bloodstream.

Anatomical system consisting of nerve bodies and nerve fibers which regulate the response of the body to external and internal stimuli.[AAO]
The nervous system is an organ system containing predominantly neuron and glial cells. In bilaterally symmetrical organism, it is arranged in a network of tree-like structures connected to a central body. The main functions of the nervous system are to regulate and control body functions, and to receive sensory input, process this information, and generate behavior [CUMBO].

Anterior end of the alimentary canal lined with smooth muscle. Bounded anteriorly by a constriction in the pharynx. Bounded posteriorly by and increase in circular and/or longitudinal smooth muscle associated with the stomach.[AAO]
The few structural specializations in (adult lampreys) pharynx include complex valves on the external gill openings that direct the tidal flow, and the division of the ancestral pharynx into an oesophagus and a respiratory pharynx.[well established][VHOG]
Tube that connects the pharynx to the stomach. In mammals, the oesophagus connects the buccal cavity with the stomach. The stratified squamous non-keratinised epithelium lining the buccal cavity is continued through the pharynx down into the oesophagus. The lowest part of the oesophagus (ca. 2 cm) is lined with gastric mucosa and covered by peritoneum. The main body of the oesophagus is lined with small, simple mucous glands. Each gland opens into the lumen by a long duct which pierces the muscularis mucosae (Wilson and Washington, 1989). A sphincter is situated at the point where the oesophagus enters the stomach to prevent gastro-oesophageal reflux, i.e. to prevent acidic gastric contents from reaching stratified epithelia of the oesophagus, where they can cause inflammation and irritation (Wilson and Washington, 1989; Brown et al., 1993).
esophagus NOT part of gut in MA. part of gut in ZFA. part_of gut (via UGIT) in FMA. Consider splitting. Interspecies: The human oesophagus is 25 cm long and has a diameter of ca. 2 cm. Only little information was found on the oesophagus in rat, rabbit and pig. The oesophagus of rat (75 x 2 mm) and rabbit has no mucous glands and the cardia of the stomach has a well-developed sphincter, which prevents them from vomiting (Hebel and Stromberg, 1988; Manning et al., 1994). Morphologically the oesophagus is similar in man and pig; both are omnivores and have a non-keratinised epithelium, submucous glands and similar membrane enzymes. Like in humans, pigs can suffer from reflux oesophagitis and stress ulceration of the oesophagus. The pig oesophagus may therefore be a good model for investigation compared to the human oesophagus (Christie et al., 1995)
Biological entity that is either an individual member of a biological species or constitutes the structural organization of an individual member of a biological species.

The zebrafish does not have a discrete pancreas. Exocrine pancreatic tissue can be found scattered along the intestinal tract. The acinar structure of the exocrine pancreas is very similar to that of mammals and comprises cells with a very dark, basophilic cytoplasm
The mature pancreas of higher vertebrates and mammals comprises two major functional units: the exocrine pancreas, which is responsible for the production of digestive enzymes to be secreted into the gut lumen, and the endocrine pancreas, which has its role in the synthesis of several hormones with key regulatory functions in food uptake and metabolism. The exocrine portion constitutes the majority of the mass of the pancreas, and contains only two different cell types, the secretory acinar cells and the ductular cells. The endocrine portion, which comprises only 1-2% of the total mass, contains five different cell types, which are organized into mixed functional assemblies referred to as the islets of Langerhans
Organ which secretes a fluid containing enzymes that aid in the digestion of food.[AAO]
An endoderm derived structure that produces precursors of digestive enzymes and blood glucose regulating hormones[GO].
In the hagfish and lampreys (our most primitive vertebrate species of today), the first sign of 'a new organ' is found as collections of endocrine cells around the area of the bile duct connection with the duodenum. These endocrine organs are composed of 99% beta cells and 1% somatostatin-producing delta cells. Compared to the more primitive protochordates (e.g. amphioxus), this represents a stage where all previously scattered insulin-producing cells of the intestinal tissue have now quantitatively migrated to found a new organ involved in sensing blood glucose rather than gut glucose. Only later in evolution, the beta cells are joined by exocrine tissue and alpha cells (exemplified by the rat-, rabbit- and elephant-fishes). Finally, from sharks and onwards in evolution, we have the islet PP-cell entering to complete the pancreas.[well established][VHOG]
As a secretory organ serving exocrine and endocrine functions, the pancreas is specific to the vertebrates[PMID:16417468] Hagfishes and lampreys are unique in the complete separation of their endocrine pancreas (islet or- gan) and their exocrine pancreas (50). The endocrine and exocrine pancreas are coassociated in crown gnathostomes (50). In Branchiostoma and Ciona, there is no diverticulum as there is in hagfishes, lampreys, and gnathostomes, only dispersed insulin-secreting cells in the walls of the gastrointestinal tract (51, 52)
Anatomical system that is a multi-element, multi-tissue anatomical cluster that consists of the skeleton and the articular system.[VSAO]

The 'new animal phylogeny' reveals that many of the groups known to biomineralize sit among close relatives that do not, and it favours an interpretation of convergent or parallel evolution for biomineralization in animals. (...) Whether this 'biomineralization toolkit'of genes reflects a parallel co-option of a common suite of genes or the inheritance of a skeletogenic gene regulatory network from a biomineralizing common ancestor remains an open debate.[debated][VHOG]
Also called osseous tissue, (Latin: os). Is a type of hard endoskeletal connective tissue found in many vertebrate animals. Bone is the main tissue of body organs that support body structures, protect internal organs, (in conjunction with muscles) facilitate movement; and are involved with cell formation, calcium metabolism, and mineral storage.[AAO]
The liquid component of blood, in which erythrocytes are suspended.
The portion of blood plasma that excludes clotting factors.
In larval lampreys, the thyroid originates as an exocrine gland, secreting its hormones into the gut, and associated with the larva's filter-feeding apparatus. In the adult lamprey, the gland separates from the gut, and becomes endocrine, but this path of development may reflect the evolutionary origin of the thyroid. For instance, the closest living relatives of vertebrates, the tunicates and Amphioxus, have a structure very similar to that of larval lampreys, and this also secretes iodine-containing compounds (albeit not thyroxine)
In tetrapods, the thyroid is always found somewhere in the neck region. In most tetrapod species, there are two paired thyroid glands - that is, the right and left lobes are not joined together. However, there is only ever a single thyroid gland in most mammals, and the shape found in humans is common to many other species
(...) at some stage of its development, every chordate exhibits five uniquely derived characters or synapomorphies of the group: (...) (2) a groove in the pharyngeal floor known as the endostyle, or a thyroid gland derived from part of the endostyle (...).[well established][VHOG]

Snakes and limbless lizards typically possess only the right lung as a major respiratory organ; the left lung is greatly reduced, or even absent. Amphisbaenians, however, have the opposite arrangement, with a major left lung, and a reduced or absent right lung [WP]
respiration organ in all air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli. // Avian lungs do not have alveoli as mammalian lungs do, they have Faveolar lungs. They contain millions of tiny passages known as para-bronchi, connected at both ends by the dorsobronchi
Respiration organ that develops as an outpocketing of the esophagus.
Lungs had already developed as paired ventral pockets from the intestine in the ancestor of Osteognathostomata. (...) In actinopterygian fishes, apart from Cladistia, the ventral intestinal pocket migrates dorsally and becomes the swim-bladder, a mainly hydrostatical organ (reference 1); Comparative transcriptome analyses indicate molecular homology of zebrafish swimbladder and Mammalian lung (reference 2).[well established][VHOG]

The liver is found in all vertebrates, and is typically the largest visceral organ. Its form varies considerably in different species, and is largely determined by the shape and arrangement of the surrounding organs. Nonetheless, in most species it is divided into right and left lobes; exceptions to this general rule include snakes, where the shape of the body necessitates a simple cigar-like form. The internal structure of the liver is broadly similar in all vertebrates.
All vertebrates possess a liver (reference 1); Later in craniate evolution, an anterior gill arch was transformed into jaws, and many new types of feeding subsequently evolved.(...) A liver evolved that, among its many functions, stores considerable energy as glycogen or lipid (reference 2).[well established][VHOG]
An organ sometimes referred to as a liver is found associated with the digestive tract of the primitive chordate Amphioxus. However, this is an enzyme secreting gland, not a metabolic organ, and it is unclear how truly homologous it is to the vertebrate liver. The zebrafish liver differs from the mammalian liver in that the hepatocytes are not clearly organized in cords or lobules and the typical portal triads are not apparent. In addition, the zebrafish liver does not have Kuppfer cells. Furthermore, a clear distinction can be made between the male and female liver in the adult zebrafish. The female hepatocytes are very basophilic (Figure 15c) as a result of the production of vitellogenin (Van der Ven et al. 2003).
Only ZFA considers this part_of immune system - we weaken this to an overlaps relation, as in general it's only a subset of cells that have clear immune function.

Membranous muscular sac in which the bile from the liver remains stored until it is required. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG]
Organ attached to the liver which stores bile and empties into the duodenum via the bile duct as needed for digestion.[AAO]
An organ that aids digestion and stores bile produced by the liver[WP].
The presence of a gallbladder appears to be a primitive trait. It is found in most fish and all adult reptiles and amphibians and has been well conserved in mammals, for the most part.[well established][VHOG]
Rats do not have a gallbladder, but produce bile. The bile flows directly from the liver through the (hepatic) bile duct into the small intestine (Hebel and Stromberg, 1988)
One of either of a pair of structures lying on either side of the dorsal aorta in which fluid balance is regulated and waste is excreted out in the form of urine.[AAO]
A paired organ of the urinary tract that produces urine and maintains bodily fluid homeostasis, blood pressure, pH levels, red blood cell production and skeleton mineralization.
The first part of the small intestine. At the junction of the stomach and the duodenum the alimentary canal is inflected. The duodenum first goes anteriorly for a short distance, turns dorsally, and eventually caudally, thus it is a U-shaped structure with two horizontal sections (a ventral and a dorsal one).
In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum.
The fixed portion of the small intestine deeply lodged in the posterior wall of the abdomen and extending from the pylorus to the beginning of the jejunum. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG]
In humans, the duodenum is a hollow jointed tube about 10-15 inches (25-38 centimetres) long connecting the stomach to the jejunum. It begins with the duodenal bulb and ends at the ligament of Treitz.
Anatomical cluster consisting of the hematopoietic system and the lymphoid system, or its analogs.
The prostate gland is a partly muscular, partly glandular body that is situated near the base of the mammalian male urethra and secretes an alkaline viscid fluid which is a major constituent of the ejaculatory fluid.
TODO - FMA treats the gland as part of the prostate - see also FMA:74119.
Anatomical structure which is found on the surface of the kidney and secretes various hormones including epinephrine, norephinephrine, aldosterone, corticosterone, and cortisol.[AAO]
Either of a pair of complex endocrine organs near the anterior medial border of the kidney consisting of a mesodermal cortex that produces glucocorticoid, mineralocorticoid, and androgenic hormones and an ectodermal medulla that produces epinephrine and norepinephrine[BTO].
suprarenal cortex manufactures corticosteroids; suprarenal medulla manufactures epinephrine and norepinephrine; suprarenal medulla receives preganglionic sympathetic innervation from the greater thoracic splanchnic n.
All craniates have groups of cells homologous to the mammalian adrenocortical and chromaffin tissues, but they are scattered in and near the kidneys in fishes. (...) The cortical and chromaffin tissues come together to form adrenal glands in tetrapods.[well established][VHOG]
The origin of the adrenal gland is still controversial. It is thought to share the same origin as the kidney and gonads, derived from coelomic epithelium of the urogenital ridge and/or the underlying mesenchyme (Keegan and Hammer, 2002; Morohashi, 1997). We follow Kardong and state homology at the level of the cortex and medulla rather than gland as a whole
Vertebrate muscle is categorized into three major muscle types defined by their structural and functional properties: skeletal, cardiac and smooth. In Dmel the counterparts are somatic, heart/cardiac and visceral. Here we take a cell type based approach.
Muscle tissue is a contractile tissue made up of actin and myosin fibers[GO].
One of the four types of tissue in traditional classifications. Tissue that contains cells with contractile filaments that move past each other and change the size of the cell. Muscle tissue also is separated into three distinct categories.[AAO]
Lymph is the fluid that is formed when interstitial fluid enters the conduits of the lymphatic system through lymph capillaries[WP].
The anteriormost subdivision of the body that includes the head, jaws, pharyngeal region and the neck (if present). In vertebrates this is the subdivision that includes the cervical vertebrae.
An anatomical structure that has more than one cell as a part.
