Myasthenia gravis is an autoimmune disorder where the immune system mistakenly attacks the neuromuscular junction, which is the area where nerves communicate with muscles. This attack leads to a decrease in the number of available acetylcholine receptors, which are necessary for muscle contractions. As a result, communication between nerves and muscles is disrupted, leading to muscle weakness and fatigue. The exact cause of Myasthenia gravis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. **
