- Relay Neurone
- Carry signals from the CNS to the Effectors.
- Motor Neurone
- Carry messages from one part of the Central Nervous System(CNS) to another

- Synapse
- A tiny gap where 2 Neurones meet, the signals cross the gap by releasing chemicals from one Neurone, and the chemical diffuses through the gap to the other Neurone, and it transmitts the signal on.
