Video - Introduction to the central and peripheral nervous systems

The central nervous system (CNS) is the part of the nervous system that consists of the brain and spinal cord. The CNS controls all voluntary muscle movement and sensations in the body. The peripheral nervous system (PNS) is the part of the nervous system that transmits signals from the central nervous system to the rest of the body, and vice versa.

The PNS consists of two parts: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements, such as walking or talking. The autonomic nervous system controls involuntary movements, such as breathing and bowel movements.
