... When an action potential arrives at the end of an axon, the sacs release the neurotransmitters into the synapse between the two cells. Neurotransmitter molecules attach to receptors on the neighboring cell. This causes positive ions to rush across the cell membrane, stimulating the cell. If the sti ...
