The Nervous System
- The human nervous system consists of the:
- Central nervous system (CNS) – the brain and the spinal cord
- Peripheral nervous system (PNS) – all of the nerves in the body
- It allows us to make sense of our surroundings and respond to them and to coordinate and regulate body functions
- Information is sent through the nervous system as nerve impulses – electrical signals that pass along nerve cells known as neurones
- A bundle of neurones is known as a nerve
- Neurones coordinate the activities of sensory receptors (eg. those in the eye), decision-making centres in the central nervous system, and effectors such as muscles and glands
