What happens as a result of ion flow at a presynaptic terminal?

Biology
1 answer:
Anarel [89]3 years ago
7 0

The correct answer is: Release of neurotrasmitters from the synaptic vesicles  

Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine), Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells.
