The central nervous system (CNS) plays a critical role in controlling the movements of the body. It consists of the brain and the spinal cord, which work together to process sensory information and coordinate responses. The brain, particularly the cerebral cortex, is responsible for complex motor functions, including planning and executing voluntary movements.

When movements are initiated, the CNS sends signals through the spinal cord to the peripheral nervous system, which carries the messages to the muscles that need to contract. This communication ensures that the body can perform coordinated movements effectively.

The peripheral nervous system does contribute to the control of movements by relaying information between the body and the CNS, but it doesn't directly manage the movements themselves. Similarly, while the sympathetic nervous system is a part of the autonomic nervous system that responds to stress and is involved in involuntary functions, it does not control voluntary movements in the way the CNS does.
