The steps of muscle contraction affected by myasthenia gravis . Concept introduction: Myasthenia gravis refers to chronic autoimmune disease that affects the skeletal muscles. It causes an error in the transmission of nerve impulses to the muscle cells when the normal communication between the nerve cell and muscle cells is interrupted at the neuromuscular junction. To form communication information in the brain cells, neurotransmittersare used. A neurotransmitter called acetylcholine releases from the end of nerve cell, when the electrical impulses proceed down a motor nerve.
