Question

Quizplus · Accepted Answer

The optic nerve is responsible for carrying visual information from the eyes to the brain, making it a sensory (afferent) nerve. Therefore, the nerve fibers sending this information belong to the sensory (afferent) division of the nervous system. The somatic nervous system refers to the division responsible for voluntary skeletal muscle movement, while the sympathetic and parasympathetic divisions are part of the autonomic nervous system, which regulates involuntary functions. None of these divisions are directly involved in the transmission of visual information.
