Question

Quizplus · Accepted Answer

Myasthenia gravis is caused by a deficiency in acetylcholine receptors, which means that the neurotransmitter acetylcholine cannot bind to receptors at the neuromuscular junction, preventing the generation of an action potential in the muscle fiber. Without an action potential, there can be no contraction of the muscle fiber. Therefore, the best choice is E, which states that there is a blockage in the generation of action potentials in the muscle fiber.
