CROSS-SPECIES ANATOMY - ANNOTATIONS

The Basic subset of the UBERON integrated, cross-species anatomy ontology is downloaded weekly from http://berkeleybop.org/ontologies/uberon/basic.obo. For more information about this ontology see the "About" page on the UBERON website at http://uberon.github.io/about.html.

Comment:[development-note] "in humans, persists as the tonsillar fossa - the endodermal lining covers the mesodermal lymphatic tissue to form the palatine tonsil[ISBN:1607950324]. the dorsal elongation of the second pouch endoderm of all mammals, with the exception of rodents, gives rise to the epithelial lining of palatine tonsils; in rodents, the ventral portion of the second pouch appears to degenerate whereas the remaining part is incorporated into the lateral border of the pharynx; it appears that rodents no longer require tonsils as their function is carried out by the NALT (Nose/Nasal-Associated Lymphoid Tissue) system in the upper respiratory tract" xsd:string {source="MP"}
Synonyms:exact_synonym: dorsal 2nd branchial pouch;   dorsal pharyngeal pouch 2
 related_synonym: dorsal branchial pouch 2 endoderm;   dorsal elongation of second pouch endoderm;   dorsal pharyngeal pouch 2 endoderm
