Question

Which of the following muscular disorders is inherited?

• A. Botulism
• B. Tetany
• C. Muscular dystrophy
• D. Myasthenia gravis

Answer 1

The correct option is C Muscular dystrophy

Muscular dystrophy is a genetic disorder that involves progressive degeneration of skeletal muscles. It affects tissues or organs, which will increasingly deteriorate over time. As it is a genetic disorder, it can be inherited.

Botulism is a rare but serious condition caused by toxins from bacteria called Clostridium botulinum that attacks the body’s nerves. Symptoms usually start with weakness of the muscles that control the eyes, face, mouth, and throat. It can also cause difficulty in breathing and even can lead to death.

Tetany is a disorder in which wild contractions or spasms of the muscles take place. This occurs due to the low calcium concentration in the body fluids.

Myasthenia gravis is an autoimmune disease in which the immune system mistakenly attacks healthy body cells. It is a neuromuscular disease which causes weakness of skeletal muscles. Eyes and faces are most commonly affected by this disorder.
