- The Nervous System
- Central Nervous System: spinal cord and brain
- Peripheral Nervous System: sensory and motor nerves.
- Electrical impulses travel along a pathway of nerve cells (neurons)
- A stimulus is detected by receptor cells inside sense organs.
- An impulse travels up a sensory neurone to a relay neurone and then to a motor neurone. This takes the impulse to effectors such as muscles.
