Definitions:

Exocytosis

The process by which cells release substances (such as neurotransmitters and hormones) outside the cell by the fusion of a vesicle with the plasma membrane.

Synaptic Vesicles

Membrane-bound sacs in neurons that store neurotransmitters, which are released into the synaptic cleft to transmit signals between neurons.

Neurotransmitters

Chemical messengers that transmit signals across a synapse from one neuron to another 'target' neuron, muscle cell, or gland cell.

Calcium Ion Influx

Calcium ion influx involves the movement of calcium ions (Ca2+) into a cell, triggering various physiological processes, including muscle contraction, neurotransmitter release, and gene expression.
