Question

The first,second,and eighth cranial nerves
A) are concerned with vision.
B) descend in the corticospinal tract.
C) are sensory nerves.
D) carry sensory information to the occipital lobe.

Accepted Answer

The first (olfactory), second (optic), and eighth (vestibulocochlear) cranial nerves are all sensory nerves. The olfactory nerve is responsible for the sense of smell, the optic nerve is responsible for vision, and the vestibulocochlear nerve is responsible for hearing and balance. None of these nerves descend in the corticospinal tract or carry sensory information to the occipital lobe.
