In anatomy, the outward-projecting point of the lower jawbone, roughly equivalent to the chin prominence.
From Greek 'exo-' meaning 'outside' combined with 'gnathion' (from 'gnathos' meaning 'jaw'). The term identifies an anatomical landmark on the external jaw structure.
Forensic anthropologists and orthodontists use exognathion as a precise measurement point on the skull to estimate age, identify individuals, and plan teeth corrections!
