Detailed explanation-1: -The peripheral nervous system (PNS) is a system of nerves which connect the central nervous system (CNS) (includes the brain and spinal cord) with other parts of the body. Reflex action is the result of the coordination of the spinal cord and peripheral nervous system. This action does not involve the brain.
Detailed explanation-2: -Spinal Cord is the center that controls reflex action. Reflex actions are actions that are carried out quickly in response to a stimulus and thus do not involve any thinking, and thus are under the control of spinal cord.
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.
