Detailed explanation-1: -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-2: -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-3: -The sensory (afferent) division carries sensory signals by way of afferent nerve fibers from receptors in the central nervous system (CNS). It can be further subdivided into somatic and visceral divisions. The somatic sensory division carries signals from receptors in the skin, muscles, bones and joints.

Detailed explanation-4: -The afferent nervous system can be divided into the visceral division, which provides information about how internal organs are functioning and sensory information about them to the brain, and the somatic division, which provides information about the skeletal and muscular system to the brain.

Detailed explanation-5: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.
