Myasthenia Gravis | Mechanism & Presentation

The video tutorial explains myasthenia gravis, a condition affecting the neuromuscular junction. Unlike other neurological diseases, it involves an autoimmune attack on acetylcholine receptors, leading to muscle weakness. The tutorial covers the mechanism of synaptic transmission, the role of calcium and sodium channels, and how antibodies disrupt this process. It also discusses the symptoms, particularly in small muscles used repetitively, and clarifies that myasthenia gravis is not a neurological condition but an acquired autoimmune disease.
