The Nervous System

Central Nervous System

The nervous system is made up of neurones.

sensory receptors: detect a change in your environment (a stimulus)

When a stimulus is detected by receptors, the info is sent as nervous electrical impulses along sensory neurones to the central nervous system (CNS).

CNS: made up of the brain and spinal cord

effector: muscle or gland

The CNS coordinates the response and sends info to an effector along a motor neurone. The effector responds accordingly.



Electrical impulses are passed
