Multiple Choice

Foramen through which the maxillary division (V2) exits the skull is?

The maxillary division exits the skull through the foramen rotundum. This round opening in the greater wing of the sphenoid marks the doorway from the cranial cavity into the pterygopalatine fossa for the second division of the trigeminal nerve. After passing through rotundum, V2 travels to give its branches in the midface, including the infraorbital nerve that emerges further anteriorly. The other openings serve different structures: foramen ovale transmits the mandibular division, jugular foramen carries IX–XI and the internal jugular vein, and foramen spinosum transmits the middle meningeal vessels (with a small meningeal branch that may associate there).
