Answer:
The somatic nervous system delivers the impulse to the skeletal muscles to produce mobility and locomotion to the body. This is what we regard as voluntary behavior. The impulse is generated in the frontal lobes of the cerebrum of the brain. This is also referred to as the motor cortex and is part of the central nervous system. It sends its impulse to the peripheral nervous system which is divided into the autonomic (involuntary) nervous system and the somatic nervous system (voluntary) and it carries out the instructions on how to move to create behavior.
ANSWER
The primary motor cortex of the frontal lobe is primarily involved in somatic motor control, however also of great importance are deeper brain structures of the basal ganglia and the cerebellum or hind brain. These areas are involved in the initiation and coordination of muscle movements as well as muscle tone. For example, damage to the cerebellum suffered at birth has been associated with muscle spasticity, while deterioration of the basal ganglia structures - in particular the substantia nigra of the mid brain, is implemented in the disease pathology and cause of some of the symptoms of Parkinson's disease.
