Normally when impulses travel down a neuron to skeletal muscle the nerve endings release acetylcholine, which crosses the neuromuscular junction and brings about the activation of muscle contraction. In myasthenia gravis the receptors for acetylcholine on the muscle cell membrane are progressively destroyed by antibodies.
