A Central Nervous System (CNS) is a nervous system (composed of CNS neurons) that integrates the received information and coordinates and influences the activity of all parts of the bodies.
- Context:
- It can (typically) be composed of a Brain and Spinal Cord.
- It can be affected by a CNS Demyelinating Disease, such as Multiple Sclerosis.
- It can be affected by a CNS Drug, such as a CNS stimulant or CNS depressant).

- The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts. It is a structure composed of nervous tissue positioned along the rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain (precursor structures exist in onychophorans, gastropods and lancelets).
The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals.
