Lab 2. Axial Skeleton: Skull Table 2. 2. Foramina associated with bones of the skull. Facial bones Foramina Bones associated Structures passing through Incisive maxilla (horizontal part, posterior to incisors) descending palatine vessels (anterior branches ); nasopalatine nerves Greater palatine palatines (at posterior angle of hard palate) descending palatine vessels (posterior branches); anterior palatine nerves Supraorbital f.
