| stimulus secretion coupling | A term used to describe the events that link receipt of a stimulus with the release of materials from membrane bounded vesicles (the analogy is with excitation contraction coupling in the control of muscle contraction). A classical example is the link between membrane depolarisation at the presynaptic terminal and the release of neurotransmitter into the synaptic cleft. (18 Nov 1997) |
