What Causes Synaptic Vesicles To Release From Their Protein Anchors? When an action potential depolarizes the presynaptic plasma membrane, Ca2 +-channels open, and Ca2 + flows into the nerve terminal to trigger the exocytosis of synaptic vesicles, thereby releasing their neurotransmitters into the synaptic cleft (Fig. … The synaptic vesicle cycle. What triggers synaptic transmission?

What Are The Steps Of Neurotransmitter Release?

by

What Are The Steps Of Neurotransmitter Release? Neurotransmitter release from the presynaptic terminal consists of a series of intricate steps: 1) depolarization of the terminal membrane, 2) activation of voltage-gated Ca2 + channels, 3) Ca2 + entry, 4) a change in the conformation of docking proteins, 5) fusion of the vesicle to the plasma membrane,
