The central nervous system is made up of the brain and spinal cord. It is the body’s main control centre, responsible for processing information, coordinating movement, regulating functions, and enabling thought, memory, and emotion.
The CNS receives sensory input from the environment, interprets it, and sends out commands through the peripheral nervous system to the rest of the body. It is protected by the skull, vertebrae, and cerebrospinal fluid.
Without the CNS, we would not be able to experience the world, react to danger, or create abstract ideas. It is the command hub of human experience and behaviour.
