Synapse
Annotation note specifics; IMMUNOLOGICAL SYNAPSES is also available; / physiol: consider also SYNAPTIC TRANSMISSION; do not confuse with SYNAPSIS see CHROMOSOME PAIRING
Scope note: Specialized junctions at which a neuron communicates with a target cell. At classical synapses, a neuron's presynaptic terminal releases a chemical transmitter stored in synaptic vesicles which diffuses across a narrow synaptic cleft and activates receptors on the postsynaptic membrane of the target cell. The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate via direct electrical coupling with ELECTRICAL SYNAPSES. Several other non-synaptic chemical or electric signal transmitting processes occur via extracellular mediated interactions.
