Acetylcholine is the neurotransmitter in the following site except: A. Sympathetic ganglia B. Parasympathetic ganglia C. Postganglionic sympathetic nerve D. Postganglionic parasympathetic nerve. Adrenaline is used in which of the following disorders?
Understand the Problem
The question is asking which site does not use acetylcholine as a neurotransmitter from the provided options, along with a separate question about the use of adrenaline in certain disorders.
Answer
C. Postganglionic sympathetic nerve; Adrenaline is used in anaphylaxis.
Acetylcholine is not the neurotransmitter at postganglionic sympathetic nerves. Adrenaline is used in anaphylaxis, cardiac arrest, and severe asthma exacerbations.
Answer for screen readers
Acetylcholine is not the neurotransmitter at postganglionic sympathetic nerves. Adrenaline is used in anaphylaxis, cardiac arrest, and severe asthma exacerbations.
More Information
Acetylcholine is used in both the sympathetic and parasympathetic ganglia as a neurotransmitter. However, in postganglionic sympathetic nerves, norepinephrine is typically used instead.
Tips
Confusing sites where acetylcholine is used can lead to incorrect answers. Remember that it is postganglionic sympathetic nerves that primarily use norepinephrine.
