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). [ ]

development notes

some AOs place this as developing from the stomodeum but we weaken this to developmental contribution, as the mouth includes non-ectodermal derivatives

external definition

Cavity in which food is initially ingested and generally contains teeth, tongue and glands.[AAO]

external ontology notes

in FMA, the tongue, palate etc are part of the mouth which is itself a subdivision of the face. ZFA includes a separate class 'oral region' which is part of the mouth, but excludes tongue and lips

homology notes

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 established][VHOG]
