Synapses

Synapses

Electrical impulses move from one neurone to the next at junctions called synapses.
- An electrical impulse reaches the end of an axon’s branch.
- The end branches convert the electrical impulse into a chemical signal called neurotransmitters, which diffuse across the synapse.
- The neurotransmitters bind to the receptors on the dendrites of the neighbouring neurone, triggering the start of an electrical impulse in the neurone.
- Once bound to receptors, the neurotransmitter is broken down by enzymes to prevent the second neurone from continually sending new electrical impulses.
