Match the following statements to the correct neurotransmitter of the autonomic nervous system. Select "Both" if the statement is true of both neurotransmitters.
Secreted by cholinergic fibers.
Receptors for this neurotransmitter may cause either excitatory or inhibitory responses.
Bind(s) to adrenergic receptors.
Receptors for this neurotransmitter are found on all autonomic postganglionic neurons.
This neurotransmitter can increase heart rate.
ANSWER OPTIONS: Acetylcholine or Norepinephrine? Both?
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.
