Central Nervous System (CNS) - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

The Central Nervous System (CNS) is a vital part of the human body that acts like the control centre for all our activities and responses. It includes the brain and spinal cord. The brain is responsible for thinking, learning, emotions, and memory, while the spinal cord helps send messages between the brain and the rest of the body. Together, they help us move, feel, and react to the world around us. The CNS processes information it receives from other parts of the nervous system and uses this information to coordinate and influence our bodily functions and responses.
