What are the characteristics of afferent neurons? Select all that apply.

Question

Quizplus · Accepted Answer

Afferent neurons are sensory neurons that carry information from sensory receptors (such as those for pressure, temperature, and pain) towards the central nervous system. They enter the spinal cord through the dorsal horn and do not exit through the ventral horns, which are reserved for motor neurons (that carry signals away from the central nervous system to muscles and glands). Therefore, choices A and D are incorrect. Afferent neurons do not extend to muscles themselves (choice B), but rather receive information from receptors that detect changes in the muscles (such as stretch receptors). Finally, choice E correctly identifies one of the primary functions of afferent neurons, namely carrying pressure sensations (and other sensory modalities) into the spinal cord.
