The central nervous system
The central nervous system is made up of the brain and spinal cord.
And the peripheral nervous system is made up of nerves and receptors.
The CNS is made up of neurons that coordinate the messages traveling through the nervous system.
The three types of cells, neurons are:
- The sensory neuron
Transmit impulses inwards from sense organs to the CNS
- Motor neurone
Transmitting impulses from the CNS to muscles and glands elsewhere in the body
- Relay neurone
Transmit the electrical impulses generated by the stimuli to other nerves.
