Rachel had injections of Botox in an attempt to eliminate facial wrinkles. Botox contains minute amounts of botulin, an extremely lethal substance produced by bacteria. Botox works because botulin blocks the release of a specific neurotransmitter from motor neurons, causing muscle paralysis. This neurotransmitter, found in all motor neurons, is called:
A) dopamine.
B) serotonin.
C) acetylcholine.
D) GABA.
