synapse

Junction between cells in the nervous system, and also between such cells and their target organs, e.g. muscles. A synapse consists of a specialised presynaptic membrane from which molecules of neurotransmitter can be released, a gap across which the neurotransmitter diffuses (synaptic cleft) and a postsynaptic membrane that has receptor molecules on it which are specific for and so bind the neurotransmitter.
