Signals across synapses

Labelled chemical synapse showing calcium entry, neurotransmitter release, receptors, reuptake, enzyme breakdown, agonist, antagonist and SSRI action

A synapse is a junction where one neurone passes a signal to another cell using a neurotransmitter. Proteins in the membranes do the key jobs, including calcium channels, receptors, enzymes and transporters.
