The two organs that make up the central nervous system (CNS) are the brain and spinal cord.
The CNS is the control center of the body. It processes information received from sensory organs and initiates responses.
-
Brain: The brain is the complex organ located in the skull responsible for higher-level functions such as thought, memory, emotion, and language. It's the primary processing unit of the CNS.
-
Spinal Cord: The spinal cord extends from the brainstem down the back and transmits signals between the brain and the peripheral nervous system. It also controls reflexes. It's the main pathway for information traveling between the brain and the rest of the body.
In short, the brain and spinal cord work together to control and coordinate all bodily functions.
