Problems of Muscular System
1. Myasthenia Gravis.

Injury-Related Muscular Problems
1. Muscle strain – “pulled muscle” is a
tearing or stretching of muscle fibers as a
result of suddenly pulling them too far.
Treatment consists of Rest, Ice,
Compress, and Elevation (R.I.C.E).
2. Bruise – discolored area under the skin
caused by leakage of blood after injury.
Ice or a cold pack can reduce the pain
and swelling of a large bruise.
Injury-Related Muscular Problems
3. Tendinitis – the inflammation of a
tendon, usually caused by overuse.
Treatment may include anti-inflammatory
medications, ultrasound, or injection of
corticosteroids.
4. Hernia – one of more serious muscle
injuries, which is protrusion of an organ
or tissue through a weak area in the
muscle. Surgery is usually required to
repair a hernia.
