Explanation:

The central nervous system (CNS) is a key part of the body's nervous system. By definition, it is composed of the brain and spinal cord. Cranial and spinal nerves are part of the peripheral nervous system. Muscles and glands are not components of the CNS. Tumors are abnormal growths and not a normal part of the CNS structure, and internal organs are not part of the CNS either.

Brain and spinal cord
