Quizplus · Accepted Answer

In myasthenia gravis, the immune system attacks the receptors for acetylcholine at the neuromuscular junction, leading to decreased muscle contraction. A drug that inhibits acetylcholinesterase, such as neostigmine, can increase the levels of acetylcholine in the synaptic cleft and compensate for the loss of receptors, leading to improved muscle function. The other choices either inhibit or block the effects of acetylcholine and would not be useful in treating myasthenia gravis.
