Preferred Label : mouth;
Uberon definition : The proximal portion of the digestive tract, containing the oral cavity and bounded
by the oral opening. In vertebrates, this extends to the pharynx and includes gums,
lips, tongue and parts of the palate. Typically also includes the teeth, except where
these occur elsewhere (e.g. pharyngeal jaws) or protrude from the mouth (tusks).;
Uberon related term : oral vestibule; vestibule of mouth; mouth cavity; oral region; trophic apparatus; stomatodaeum; rima oris; stoma; cavum oris; cavitas oris; vestibulum oris;
Uberon narrow term : adult mouth;
Uberon Development note : some AOs place this as developing from the stomodeum but we weaken this to developmental
contribution, as the mouth includes non-ectodermal derivatives;
Uberon Homology note : Molecular and developmental cell lineage data suggest that the acoel mouth opening
is homologous to the mouth of protostomes and deuterostomes and that the last common
ancestor of the Bilateria (the 'urbilaterian') had only this single digestive opening.[well
