Myasthenia gravis is a neuromuscular disorder or autoimmune disorder. An autoimmune disorder occurs when the immune system mistakenly attacks its own healthy tissue. Neuromuscular disorders involve the muscles and the nerves that control them. With myasthenia gravis, the body produces antibodies that block the muscle cells from receiving messages (neurotransmitters) from the nerve, which causes weakness of the voluntary muscles. Therefore, fewer receptors are available for stimulation, resulting in voluntary muscle weakness that escaltes with continued activity (Hinkle & Cheever, 2013). Myasthenia gravis can affect people at any age but is most common in young women and older men. The muscle weakness of myasthenia gravis worsens
