In the parasympathetic branch of the autonomic nervous system, there are two cholinergic synapses (synapses mediated by acetylcholine) on the way to the target tissue. The first synapse is in the autonomic ganglion (from the "preganglionic neuron"), and is always mediated by nicotinic acetylcholine receptors (NACHRS). The second synapse (from the "postganglionic neuron") is on the target cell, and is mediated by muscarinic acetylcholine receptors (mAChRs). A. Which of these synapses is expected to always produce a rapid depolarization of the postsynaptic cell? Explain your answer.

Question
Transcribed Image Text:In the parasympathetic branch of the autonomic nervous system, there are two cholinergic synapses
(synapses mediated by acetylcholine) on the way to the target tissue. The first synapse is in the
autonomic ganglion (from the "preganglionic neuron"), and is always mediated by nicotinic
acetylcholine receptors (NACHRS). The second synapse (from the "postganglionic neuron") is on the
target cell, and is mediated by muscarinic acetylcholine receptors (mAChRs).
A. Which of these synapses is expected to always produce a rapid depolarization of the
postsynaptic cell? Explain your answer.
