Question

Which of the following is true of CNs III,IV,and VI? All
A) are sensory and send information to the primary visual cortex.
B) stimulate the levator palpebrae superioris to raise the eyelid.
C) send information to the occipital lobe.
D) move the eyeballs.

Accepted Answer

CN III (oculomotor nerve), CN IV (trochlear nerve), and CN VI (abducens nerve) are all motor nerves responsible for moving the eyeballs. They are not sensory nerves and do not send information to the primary visual cortex or occipital lobe. They also do not stimulate the levator palpebrae superioris to raise the eyelid.
