Definition
English
:
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.
