Describe the process of synaptic transmission.

An action potential travels down the axon of the presynsaptic neurone. It stimulates the vesicles to bind to the pre synaptic membrane and release their neurotransmitters into the synaptic cleft. They diffuse across the gap and bind to complementary receptors on the post synaptic neurone. This binding stimulates a new action potnetial to travel down the post synaptic neurone.
