Question

Quizplus · Accepted Answer

Myasthenia gravis is caused by the production of antibodies against the ligand-gated channels on the postsynaptic membrane at the neuromuscular junction. These channels normally bind acetylcholine released by the presynaptic neuron, allowing the opening of ion channels that trigger muscle contraction. By blocking or reducing the function of these channels, the antibodies disrupt the neural transmission and cause weakness and fatigue in affected muscles. The other choices are not specific to myasthenia gravis or do not accurately reflect the underlying mechanism of the disease.
