Parasympathetic Medications and Cholinergic Concepts

Vocabulary review covering key terms related to the parasympathetic system, acetylcholine, and cholinergic pharmacology from the lecture notes.

Parasympathetic response

The rest-and-digest branch of the autonomic nervous system, mediated by acetylcholine at parasympathetic targets.

Acetylcholine

Neurotransmitter used by the parasympathetic nervous system; activates muscarinic and nicotinic receptors.

Acetylcholinesterase

Enzyme that rapidly breaks down acetylcholine in the synaptic cleft, terminating cholinergic signaling.

Cholinergic agents

Drugs that mimic or enhance acetylcholine at cholinergic receptors, directly or indirectly.

Acetylcholinesterase inhibitors

Drugs that inhibit acetylcholinesterase, increasing acetylcholine levels and prolonging cholinergic effects.

Inhibit the parasympathetic response

Pharmacologic effect where parasympathetic activity is reduced; can involve receptor blockade or decreased acetylcholine action.
