The symptoms make the muscle weakness come and go. The symptoms usually reaching to their worst within a few year after the onset of the disease and the symptom tend to progress over time. Although myasthenia gravis can affect any of the muscles that you control voluntarily, certain muscle groups are more commonly affected than others. The people who suffered Myasthenia Gravis may have variable symptoms depending on the involvement of diseases that affecting certain muscles or multiple muscle groups. The disease that affected certain eye muscle was described as ‘ocular myasthenia gravis’.
Part 3: What Are the Symptoms of Myasthenia Gravis? Myasthenia gravis affects voluntary muscles, and the muscles that control eyelid movement, swallowing, and facial expression are most frequently affected. The onset of symptoms may be sudden and may not be immediately recognized as myasthenia. The first symptom is often weakness of the eye muscles, which may vary greatly among individuals.

Bronchial asthma, emphysema, chronic bronchitis are important disorders came under this group 2. RESTRICTIVE DISEASES Diseases which interfere with normal ventilation by restricting the expansion of thoracic cage, lungs and pleura are included in this group. Total lung capacity is decreased in this disease. The conditions like kyphoscoliosis, pleural effusion result in compression of lung and diminished expansion of thoracic
Skeletal muscle fibers can be classified into type 1 fibers, type II(a) fibers and type II(b) fibers. Type 1 fiber (slow oxidative fiber) It contract relatively slow because its myosin ATPases are slow. It depends on oxygen delivery and aerobic pathways and is fatigue resistant
