Study Question

A minature end plate potential (MEPP) is :

Which of the following

A quantal depolarization that occurs at the specialized region of a muscle fiber (end plate) at a neuromuscular junction.

Is produced by the activation of post-synaptic receptors by the ligand acetylcholine (a neurotransmitter)

Causes hyperpolarization of the muscle cell membrane

is the result of sodium and potassium flux through post synaptic acetylcholine receptors

generates an action potential across the muscle fiber membrane
