Neurotransmitter

Chemical substances released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.

Ion

An atom or molecule with a net electric charge due to the loss or gain of one or more electrons, essential in a wide array of biological processes.

Acetylcholinesterase

Enzyme found in the synaptic cleft that causes the breakdown of acetylcholine to acetic acid and choline, thus limiting the stimulatory effect of acetylcholine.
