Explanation:
Detailed explanation-1: -The afferent or sensory division transmits impulses from peripheral organs to the CNS. The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action.
Detailed explanation-2: -The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
Detailed explanation-3: -The PNS has two components, a sensory (afferent) and a motor (efferent) component. The sensory component, also known as the afferent component (ad meaning to +ferre meaning carry), is responsible for conveying information to the CNS from the body itself and from the environment (Fig. 1).
