Answer: FALSE

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
