Quizplus · Accepted Answer

Afferent neurons carry information from the periphery (such as sensory receptors in the skin) to the central nervous system (CNS).

Answer: A 
 Ascending tracts also carry sensory information (such as touch, temperature, and pain sensations) from the periphery to the CNS.

Answer: B 
 Descending tracts are sensory pathways that transmit nerve impulses from the brain down the spinal cord to control the movement of muscles.

Answer: D 
 Efferent neurons are motor neurons that transmit signals from the CNS to the peripheral nervous system (PNS), which controls voluntary and involuntary movements.
