- How the nervous system coordinates responses
- the central nervous system consists of the brain and the spinal cords
- it allows us to make sense of our surroundings in order to survive
- 1. receptor cells convert a stimulus (e.g bright light) into an electrical impulse
- 2. This electrical impulse travels alongside cells called sensory neutrons to the central nervous system
- 3. Here, the information is processed and the appropriate response is coordinated, resulting in an electrical impulse being sent along motor neurones to effectors
- 4. The effectors carry out the response (e.g muscles contracting or glands secreting hormones)
