List the disorders of muscular system.

Explanation

Disorders of muscular system:
1. Myasthenia gravis: An autoimmune disorder affecting the action of acetylcholine at neuromuscular junction leading to fatigue, weakening and paralysis of skeletal muscles.
2. Tentany : Rapid muscle spasms occur in the muscles due to deficiency of parathyroid hormone resulting in reduced calcium leavels in the body.
3. Muscle fatigue: Muscle fatigue is the inability of a muscle to contract after repeated muscle contractions.
4. Atrophy: A decline or cessation of muscular activity results in the condition called atrophy which results in the reduction in the size of the muscle and makes the muscle to become weak, which occurs with lack of usage as in chronic bedridden patients.
5. Muscle pull: Muscle pull is actually a muscle tear. A traumatic pulling of the fibres produces a tear know as sprain. This can occur dur to sudden stretching of muscle beyond the point of elasticity.
6. Musclar dystrophy: The group of diseases collectively called the muscular dystrophy are associated with the progressive degeneration of skeletal muscle fibres, weakening the muscles and leading to death from lung or heart failure.
