What is the cause of weakness in muscles?
Myasthenia gravis impairs the transmission of signals from nerves to muscles at a site called the neuromuscular junction (NMJ), where nerves make contact with muscle. This causes temporary weakness of muscles in use. When the affected muscle or muscle group is rested, it recovers strength. Throughout the day, your body uses many muscle groups ...
Why is myasthenia gravis worse?
Because myasthenia gravis is marked by use-related weakness in particular muscle groups, repeated activity of affected muscle makes weakness worse. The weakness improves with rest, only to recur as activity resumes. Which muscle groups are affected may vary from person to person. Often, the muscles around the eyes are affected.
What is the protein that attacks the junction of myasthenia gravis?
If you have autoimmune MG, your immune system produces antibodies that inappropriately attack certain proteins at the junction. One such protein is the acetylcholine receptor (AchR), located on the muscle membrane at the junction.
What is the best treatment for achy spondyloma?
Treatment is directed first toward improving symptoms. The drug most commonly used is pyridostigmine. Pyridostigmine prolongs the time that Ach stays in the neuromuscular junction, thus giving it more of a chance to bind to the reduced number of AchR receptors.
