MUSCLE PHYSIOLOGY

Detailed explanation-1: -MG may present as unilateral ptosis or facial drooping without the hallmark characteristic of fluctuating muscle weakness. Early diagnosis and subsequent treatment of MG improves long term prognosis and remission rates.

Detailed explanation-2: -The most commonly affected muscles are the levator palpebrae superioris, extraocular muscles, orbicularis oculi, muscles involved in facial expressions, mastication, speech, neck extensor muscles, and proximal limb muscles (triceps, deltoid, iliopsoas). The most common presenting symptoms are also found to be ocular.

Detailed explanation-3: -Numbness, heaviness, muscular spasm, or loss of control of the limb can be experienced by the myasthenic. Limb weakness is often not symmetrical, with one side being weaker than the other.
