Synapse. Illustration of a synapse,the junction between two nerve cells . Other nerve cell bodies are present (branched,with mauve nuclei). Synapses transmit electrical signals from one nerve cell to the next. When an electrical signal reaches a synapse it triggers the release of chemicals called neurotransmitters (red) from vesicles (pink) in the terminal swelling of the presynaptic cell. The vesicles burst through the membrane,& neurotransmitters cross a microscopic gap called the synaptic cleft,and bind to the receptor nerve cell. The neurotransmitter changes the permeability of the postsynaptic membrane,causing it to propagate an electrical impulse | |
