Explanation: 

Detailed explanation-1: -A somatic reflex is an involuntary response to a stimulus, such as pulling one’s hand away after touching a hot stove. The nervous system is split into the central nervous system (i.e., the brain and spinal cord) and the peripheral nervous system (i.e., nervous system outside of the brain and spinal cord).

Detailed explanation-2: -The somatic nervous system is part of the peripheral nervous system and plays a role in voluntary movements and sensory processing. The somatic nervous system carries motor and sensory signals to and from the central nervous system (CNS).

Detailed explanation-3: -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. Besides these, there are thousands of other association nerves in the body.
