Myasthenia gravis is a chronic autoimmune muscular disease. It causes
breakdown of neuromuscular junction due to which the brain loses control over muscles. The symptoms may include drooping eyelids, difficulty in swallowing muscle fatigue, difficult breathing and inability to control facial expressions.

Myasthenia gravis is an autoimmune neuromuscular disorder that affects the transmission of nerve impulses to muscles. The correct statement regarding disorders of muscles in humans is:
b) Failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing.
Explanation:
Myasthenia gravis is characterized by the weakness and fatigue of skeletal muscles, especially those that are responsible for controlling eye movements, facial expressions, chewing, swallowing, and breathing. The disorder occurs when the immune system mistakenly attacks the receptors that are located at the neuromuscular junction, where the nerve cells meet the muscle cells.
As a result, the transmission of nerve impulses to the muscles is disrupted, leading to muscle weakness and fatigue. In severe cases, the muscles that are responsible for breathing may also be affected, leading to respiratory failure, which can be life-threatening.
One of the common symptoms of myasthenia gravis is difficulty in swallowing, which is known as dysphagia. This occurs because the muscles that control swallowing are weakened, making it difficult to move food and liquids from the mouth to the stomach. As a result, people with myasthenia gravis may have trouble eating and drinking, leading to malnutrition and dehydration.
Other symptoms of myasthenia gravis include:
- Weakness in the arms, legs, and neck
- Double vision or drooping eyelids
- Difficulty speaking or breathing
- Fatigue that worsens with activity and improves with rest
Treatment for myasthenia gravis includes medications that improve the transmission of nerve impulses, such as acetylcholinesterase inhibitors and immunosuppressive drugs. In severe cases, plasma exchange or intravenous immunoglobulin may be needed to remove the antibodies that are causing the autoimmune reaction.
In conclusion, the correct statement regarding disorders of muscles in humans is that failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing.
b) Failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing.
