the superior orbital fissure

7

*What are the contents of the foramen rotundum?

the maxillary division of the trigeminal nerve (cranial nerve Vb)

What opening allows a branch of cranial nerve VII to enter the pterygopalatine fossa from the middle cranial fossa?

the vidian canal/pterygoid canal

17

What are the contents of the hiatus for the lesser petrosal nerve?

the lesser petrosal nerve, a branch of the tympanic plexus from the glossopharyngeal nerve

18

What will the foramen ovale communicate with?

the middle cranial fossa and infratemporal region
