Sample questions

1. Which of the following is the PRIMARY function of acetylcholinesterase at cholinergic synapses?

a.Synthesizing acetylcholine from choline and acetate

b.Binding to muscarinic receptors to initiate a response

c.Releasing acetylcholine into the synaptic cleft

d.Terminating the signal by hydrolyzing acetylcholine into choline and acetic acid

2. A patient is diagnosed with glaucoma. Which of the following direct-acting muscarinic agonists is MOST appropriate for topical use to increase aqueous humor outflow?

a.Pilocarpine, because it is a naturally occurring alkaloid with a longer duration of action

b.Carbachol, because it has both muscarinic and nicotinic effects

c.Acetylcholine, because it is the natural neurotransmitter

d.Methacholine, because it is resistant to hydrolysis

3. Which of the following statements about the muscarinic receptor subtypes is CORRECT?

a.M3 receptors are coupled to Gi proteins to decrease cAMP formation

b.All five identified muscarinic receptors have well-defined physiological functions

c.M1, M2, and M3 are the subtypes known to have physiological functions

d.M2 receptors are primarily located on exocrine glands and smooth muscle

4. The mechanism by which acetylcholine causes a decrease in heart rate involves which of the following sequences?

a.Activation of M3 receptors → stimulation of phospholipase C → increased intracellular calcium

b.Activation of M2 receptors → Gi protein activation → opening of potassium channels and inhibition of adenylyl cyclase

c.Activation of M1 receptors → Gi protein inhibition → increased cAMP formation

d.Activation of nicotinic receptors → sodium influx → depolarization of pacemaker cells

5. Which of the following is NOT a characteristic of the choline ester bethanechol?

a.It possesses significant nicotinic receptor activity

b.It has an amide group substituting the acetyl group of acetylcholine

c.It is a synthetic derivative of acetylcholine

d.It has a methyl group added to the beta carbon of acetylcholine
