Question

Cranial nerve II, the optic nerve sends nerve impulses to the brain carrying information about the things we see. These nerve fibers most likely belong to which division of the nervous system?A) sensory (afferent) divisionB) somatic nervous systemC) sympathetic divisionD) parasympathetic division

Answer 1

Answer:

A) sensory (afferent) division

Explanation:

The peripheral nervous system has two distinct divisions with different functions. The sensory or afferent division is one of them. The sensory or afferent division serves to deliver the sensory information from the receptors to the central nervous system. The neurons that carry sensory information are called sensory neurons. Cranial nerve II carries the sensory impulses about vision from the retina to the brain (a part of the central nervous system). This makes this nerve a component of the sensory division of PNS.
