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…
