Afferent nerves are what type of nerves?

Afferent nerves are what type of nerves?

• A. Motor nerves
• B. Sensory nerves
• C. Autonomic nerves
• D. Mixed nerves

Answer: (B)

Afferent nerves carry information from peripheral sensory receptors toward the central nervous system, so they are sensory nerves. They convey signals like touch, temperature, pain, and proprioception from the body to the brain or spinal cord for processing. In contrast, efferent nerves carry commands from the CNS to muscles and glands, producing motor output. Some nerves can contain both types of fibers (mixed nerves), but the term afferent specifically describes sensory input toward the CNS.
