Verified step by step guidance1
Begin by understanding the parasympathetic nervous system, which is part of the autonomic nervous system responsible for 'rest and digest' functions.
Recognize that the parasympathetic system primarily uses acetylcholine as its neurotransmitter.
Identify the two main types of cholinergic receptors that respond to acetylcholine: nicotinic and muscarinic receptors.
Nicotinic receptors are ionotropic receptors found at the neuromuscular junction and in the autonomic ganglia.
Muscarinic receptors are metabotropic receptors found in various target organs and tissues, mediating the effects of the parasympathetic system.
