Synapses
- Where two neurones meet, they do not actually come into physical contact with each other
- Instead, a very small gap, known as the synaptic cleft, separates them
- The ends of the two neurones, along with the synaptic cleft, form a structure known as a synapse
- Synapses act as the junctions between any cells in the nervous system, e.g.
- In the sense organs, there are synapses between sensory receptor cells and sensory neurones
- In muscles, there are synapses between motor neurones and muscle fibres
