Function notes: The seminal vesicles secrete a significant proportion of the fluid that ultimately becomes semen. Lipofuscin granules from dead epithelial cells give the secretion its yellowish color. About 50-70%[2] of the seminal fluid in humans originates from the seminal vesicles, but is not expelled in the first ejaculate fractions which are dominated by spermatozoa and zinc-rich prostatic fluid. +
Taxon notes (from WP): Most vertebrates have some form of duct to transfer the sperm from the testes to the urethra. In cartilaginous fish and amphibians, sperm is carried through the archinephric duct, which also partially helps to transport urine from the kidneys. In teleosts, there is a distinct sperm duct, separate from the ureters, and often called the vas deferens, although probably not truly homologous with that in humans. In cartilaginous fishes, the part of the archinephric duct closest to the testis is coiled up to form an epididymis. Below this are a number of small glands secreting components of the seminal fluid. The final portion of the duct also receives ducts from the kidneys in most species. In amniotes, however, the archinephric duct has become a true vas deferens, and is used only for conducting sperm, never urine. As in cartilaginous fish, the upper part of the duct forms the epididymis. In many species, the vas deferens ends in a small sac for storing sperm. The only vertebrates to lack any structure resembling a vas deferens are the primitive jawless fishes, which release sperm directly into the body cavity, and then into the surrounding water through a simple opening in the body wall. +
Zebrafish epidermis consists only of living cells unlike terrestrial vertebrates in which dead, keratinized cells are present. In terrestrial vertebrates the epidermis often forms an outer keratinized or cornified layer, the stratum corneum. Interaction between the epideris and dermis gives rise to feathers (birds), hair and mammary glands (mammals), teeth and scales (placoid: chondrichthyans; cosmoids, ganoid, cycloid in bony fishes). +
This class generically groups trachea and analagous structures throughout metazoa. Consider renaming, as the term could be taken to mean lumen of tracheal system (e.g. in SNOMED) +
note that many anatomy ontologies consider gastrointestinal system synonymous with digestive system. here we follow MA in dividing digestive system into gastrointestinal and hepatobiliary. hepatobiliary includes the liver and biliary tract. species-specific AO classes are categorized according to whether liver is included. For example, XAO includes liver as part of XAO:0000125 alimentary system, so we assume this class is the more generic class +
In various sources such as Encyclopedia Britannica, the excretory and urinary systems are indeed the same system (see wikipedia talk page); we merge two BTO classes here +
These markers are associated with human cells. Originally described in the dendritic cell ontology (DC_CL:0000026)(PMID: 19243617). These cells are also CD281-positive (TLR1), CD282-positive (TLR2), CD284-positive (TLR4), CD286-positive (TLR6), CD287-positive (TLR7), and CD290-positive (TLR10). When activated, these cells are capable of producing IL-6, IL-8, and IL-15. +
AO notes: In FMA this is classified as a set of organs. ZFA musculature system has subtypes, so it is classified here. WBbt muscular system has subtypes so it goes here. Note that we use the MA term set of skeletal muscles here as it seems most appropriate (*not* MA:musculature). AAO is generally confused here. +
check nerve vs peripheral nerve vs tract. Check isa hierarchy - we include under neural tissue as well as neuron projection bundle for now. FMA also has this under organ segment +
