Markers: CCR2-CX3CCR1+ (human, mouse, rat); human: CD16+, CCR5+, CD32/FcgRII-high, MHCII+, CD86+; mouse: CD62L-Ly6C-. +
These cells have not been exposed to antigen following thymic T-cell selection; found in blood and secondary lymphoid organs. +
Usage notes: note that we use the slightly verbose term 'thoracic segment of trunk' to avoid confusuon with insect thorax. todo - taxonomic constraints. Also, in FMA 'thorax' is a synonym for chest +
Taxon notes: Vertebrate specific. In arthropods 'abdomen' is the most distal section of the body which lies behind the thorax or cephalothorax. If need be we can introduce some grouping class +
Obsoleted in ZFA. Note that embryo is not classified as an embryonic structure - an embryonic structure is only the parts of an embryo +
Taxon notes: sponges do not seem to have a mesoderm and accordingly Amphimedon lacks transcription factors involved in mesoderm development (Fkh, Gsc, Twist, Snail)[http://www.nature.com/nature/journal/v466/n7307/full/nature09201.html]. Mesoderm may not be homologous across verteberates[UBERONREF:0000002] +
Editor note: consider indicating location. e.g. anterior. Note some AOs place this as part of oral opening, but it's not clear when this structure comes into existence. Taxon note: This class groups together disparate structures as all being the anterior part of the early metazoan digestive tract and precursor of the mouth. However, the developmental processes vary, so this class may be split in future. E.g. in mammals it is a rostral depression surrounded by prominences. Outgrowth of the prominences produces a stomodeal cavity. +
AO notes: (relaion to eye): MA, XAO, AAO and BTO consider this part of the eye. This is in contrast to GO, FMA, EHDAA2 (FMA has a class 'intra-ocular part of optic nerve' which represents the region of overlap). Relation to brain: part of diencephalon in EHDAA2, ZFA. In NIF, has the optic nerve root as part, which is a feature part of the diencphalon. Structure notes: We are consistent here with the FMA in considering CN-II continuous with the retina. Editor notes: - determine the precise relationship between CN II and the CNS +
Types of B lineage lymphocytes include B cells and antibody secreting cells (plasmablasts and plasma cells). +
Taxon notes: 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 -- Stomach#In_other_animals +
Terminology notes: Rector et al: One might be tempted to define 遯ｶ蠕Ｆart valve遯ｶ� equivalently to 遯ｶ蠢ｻalve in the heart遯ｶ�, and 遯ｶ蠢ｻalve遯ｶ� as a 遯ｶ蠕ｭtructure which functions as a valve遯ｶ�. But this combination results in the 遯ｶ蠖ｷoramen ovale遯ｶ� being classified as a kind of 遯ｶ蠕Ｆart valve遯ｶ�, since it is undoubtedly located in the heart and functions as a valve +
Editor notes: This class is currently a mixed bag, encompassing (1) the entirety of the mammalian aorta together with (2) the developmental and phylogenetic homologs of its segments: the ventral aorta and dorsal aortae. Taxon notes: All amniotes have a broadly similar arrangement to that of humans, albeit with a number of individual variations. In fish, however, there are two separate vessels referred to as aortas. The ventral aorta carries de-oxygenated blood from the heart to the gills; part of this vessel forms the ascending aorta in tetrapods (the remainder forms the pulmonary artery). A second, dorsal aorta carries oxygenated blood from the gills to the rest of the body, and is homologous with the descending aorta of tetrapods. The two aortas are connected by a number of vessels, one passing through each of the gills. Amphibians also retain the fifth connecting vessel, so that the aorta has two parallel arches[WP]. +
