Check Point: Acetylcholine is the primary neurotransmitter for the PNS that transmits neural impulses. Its name is derived from its chemical structure: ester of acetic acid and choline. Parts in the body that use or are affected by acetylcholine are referred to as cholinergic. Substances that increase or decrease the overall activity of the cholinergic system are called 'cholinergics' and 'anticholinergics', respectively Cholinergenics stimulate: can see, can shit, can spit Anti-cholinergenics slow: can't see, can't shit, can't spit

Cholinergic>mimic acetylcholine and create a stimulative effect such as muscle contraction, heart rate deceleration, constriction of the iris and of the lens, mucus secretion and broncho-constriction. Anticholinergenics >inhibit the action of acetylcholine and work to slow the autonomic nervous system. Such as the involuntary tremors and muscle stiffness associated with diseases like Parkinson's.
