What Are the Effects of Nonquantal Release of Acetylcholine at the Neuromuscular

question 10

Multiple Choice

What are the effects of nonquantal release of acetylcholine at the neuromuscular junction?

• A) This nonquantal release creates a slow dribble of ACh that has no effects on the postsynaptic muscle cell because it is degraded by acetylcholinesterase.
• B) This nonquantal release creates a slow dribble of ACh that depolarizes the postsynaptic muscle cell because it escapes being degraded by acetylcholinesterase.
• C) This nonquantal release creates a large amount of ACh that can cause the postsynaptic muscle cell to fire an action potential.
• D) This nonquantal release is much less than is released during spontaneous quantal release (mEPPs).
• E) Nonquantal release does not occur at the neuromuscular junction.
