Final answer:
The somatic nervous system is associated with conscious and voluntary activities, and it relays sensory and motor information to and from the central nervous system.
Step-by-step explanation:
b. The somatic nervous system is associated with conscious and voluntary activities, and it is involved in relaying sensory and motor information to and from the central nervous system. Motor neurons carry instructions from the CNS to the muscles, while sensory neurons carry sensory information to the CNS. The somatic nervous system consists of both efferent (moving away from) and afferent (moving toward) fibers, forming a two-way superhighway of neurons.
