This neurotransmitter is chiefly used in the sympathetic nervous system

• Glutamate

• Epinephrine

• Norepinephrine

• GABA

Parasympathetic neurotransmitter

• Epinephrine

• Norepinephrine

• Acetylcholine

• Glutamate

The effects of this division of the ANS are typically localized; they may be limited to one organ

• Sympathetic

• Parasympathetic

• Enteric

• Somatic

Plexuses are made up of the tangled networks of which division of the ANS

• Parasympathetic

• Sympathetic

• Neither

• Both

• Bronchospasm

• Tachycardia

• Acute hypertension

After a period of intense exercise, you notice that your turbinate edema that you attribute to seasonal allergies has returned. Your provider explains that vasodilation during activity helps to circulate allergens away faster. The binding of which neurotransmitter to which type of receptor is most likely to have had the greatest impact on your allergies?

• Acetylcholine; alpha 1

• Norepinephrine, alpha 2

• Norepinephrine, beta 2

• Epinephrine, beta 2

Answer explanation

After a stressful day at CCP, you get home and collapse into bed. After a few minutes, your smart watch vibrates to notify you of a sudden and unexpected bradycardia. Setting pathophysiology aside, what is the most likely explanation for this?

• Stimulation of the sympathetic nervous system

• Stimulation of the parasympathetic nervous system

• Stimulation of the somatic nervous system

• Stimulation of the enteric nervous system
