The outer wall of the braincase becomes the alisphenoid and the dermal skull bones. |
|
The bullae are sometimes not ossified, and when they are, they are formed largely by extensions from the alisphenoid. |
|
Posteromedial to the glenoid surface, the foramen ovale opens in the alisphenoid. |
|
The posterior part of each alisphenoid forms a triangular process which fits into the angle between the squamosal and the petrosal. |
