Neurones

HideShow resource information
Sensory Neurones
Nerve cells that carry signals as electrical impulses from the receptors in the sense organs to the CNS
1 of 6
Relay Neurones
The nerve cells that carry signals from the sensory neurones to the motor neurones
2 of 6
Motor Neurones
The nerve cells that carry signals from the CNS to the effector muscles or glands
3 of 6
Effectors
Muscles and glands are known as effectors- they respond in different ways. Muscles contract in response to a nervous impulse, whereas glands secrete hormones
4 of 6
Central Nervous System
Where all the information from the sense organs is sent and where reflexes and actions are coodinated
5 of 6
What does the CNS consist of?
The brain and spinal cord only
