Axon Types Practice Test

GVE-P fibers are parasympathetic motor efferents to smooth muscle and glands. They carry autonomic signals that regulate visceral organs, commanding actions like smooth muscle contraction and gland secretion. These fibers originate in the brainstem or sacral spinal cord and synapse in autonomic ganglia near the target tissue, with postganglionic neurons releasing acetylcholine to produce the effect.

This is why the correct function is parasympathetic motor to smooth muscle and glands. The other options describe sensory or somatic motor pathways (general somatic afferent, somatic motor to skeletal muscle, special visceral afferent) and do not match the autonomic parasympathetic efferent role of GVE-P.
