The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.
Parts of the nervous system includes:
--> Central Nervous System ( consists of the brain and spinal cord)
--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).
The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE
