The Main Organs The main organs of the nervous system are, the brain, the spinal cord and the nerves. The brain functions to keep your memory. The spinal cord helps you keep balance. The nerves function for you to be able to feel things.
The anatomy of the nervous system in humans consists of the brain and spinal cord, along with the primary sense organs and all the nerves associated with these organs. The brain and the spinal cord form the central nervous system (CNS). All other neuronal tissue is brought under the umbrella of the peripheral nervous system (PNS).
The central nervous system is made up of the brain, the spinal cord and even the retina, and it is directly responsible for the translation of the messages sent by the peripheral nervous system, which is the network of nerves that run throughout the body.
