Detailed explanation-1: -The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.
Detailed explanation-2: -The motor division of the PNS carries nerve impulses from the central nervous system to muscles and glands throughout the body. The nerve impulses stimulate muscles to contract and glands to secrete hormones.
Detailed explanation-3: -The PNS is made up of two divisions: the somatic nervous system and the autonomic nervous system. The somatic system contains sensory and motor neurons. It sends and receives sensory information and motor signals. The autonomic system is responsible for regulating involuntary body functions.
Detailed explanation-4: -The sensory division of the PNS is also known as the efferent division. All of the sensory information is considered afferent, or flowing toward the CNS. Efferent means “from the CNS.” Three main levels of neural integration operate in the somatosensory system.
