Terminal button
The end of an axon (long, fiber-like extension) of a nerve cell is called a terminal bouton if it is the presynaptic part of a synapse. The terminal bouton is a spherical thickening containing vesicles (small sacs) that store neurotransmitters (chemical messengers in the brain).

Action potential
In excitable cells (e.g., neurons or muscle cells), very rapid changes in electrical potential occur across the cell membrane. This event is the basis for signal conduction along the axon of the nerve cell. The action potential continues along the cell membrane and, according to the all-or-nothing principle, only occurs when the cell has been sufficiently excited.

Amacrine cells
Amacrine cells are interneurons of the retina. They are located between photoreceptors and bipolar cells on the one hand and ganglion cells on the other. The name was coined by Ramón y Cajal and means "without axon."
