CNS (central nervous system)

The central nervous system (CNS) is the body's main control center, made up of the brain and spinal cord. It processes information received from the body and the environment, then sends out instructions to coordinate actions, thoughts, feelings, and bodily functions. The CNS is essential for thinking, memory, emotions, and movement. The brain interprets signals and makes decisions, while the spinal cord acts as a communication highway, transmitting messages between the brain and the rest of the body. It is protected by the skull and vertebral column, ensuring it can perform its vital roles effectively.
