Pharyngeal fossa

Last revised by Francis Deng on 8 Sep 2020

The pharyngeal fossa or foveola pharyngica is a variant oval or round depression within another inconstant bony excavation, the fossa navicularis, on the ventral surface of the basioccipital clivus.

A prominent appearance of the pharyngeal fossa may be indistinguishable from the nasopharyngeal end of an incomplete canalis basilaris medianus, thought to be due to a remnant of the notocord 1-3.
