Myasthenia Gravis : It is an autoimmune disorder in which the antibodies produced in the body start attacking its own body cells. The antibodies recognise the body cells as foreign material and start acting against it. In myasthenia gravis, the antibodies start attacking the acetylcholine receptors present on sarcolemma, due to which the neurotransmitter (i.e., acetyl choline) could not bind to its receptor and hence, could not initiate nerve transmission. The skeletal muscle in patients become weak and leads to paralysis.
