The nervous system consists of two major parts: the central nervous system and the peripheral nervous system.
Explanation:
In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.
It is the motor cortex of the brain that controls the voluntary movements of the body. It is in the rear part of the frontal lobe and is a region in the cerebral cortex. It is responsible for planning, control and the execution of the voluntary movements in the body.
