Quizplus · Accepted Answer

Cranial nerves III, IV, and VI all exit the cranium through the superior orbital fissure, which is a narrow, slit-like opening located in the posterior part of the orbit. This allows them to control the movement of the eye muscles and contribute to vision. The optic canal (A) is where the optic nerve exits, the internal acoustic meatus (B) is where the facial nerve and vestibulocochlear nerve exit, and the inferior orbital fissure (D) allows passage of blood vessels and nerves to the face.
