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 somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]. It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions.
Detailed explanation-3: -The sensory division senses both the internal environment and the external environment. It is sometimes called the afferent division because it conducts information into the CNS. The motor division is the efferent division because it conducts information out of the CNS to effectors such as muscles and glands.
Detailed explanation-4: -The nerves that communicate sensor and motor signals between the central nervous system and rest of the body are collectively referred to as peripheral nervous system (PNS). Sensory inputs are received by receptor cells located in sensory organs.
