Question

Name the autoimmune disorder that affects the skeletal muscles in humans.

Hint:

Do not confuse this with Muscular Dystrophy, which is a genetic disorder, not autoimmune.

Answer 1

Step 1: Understanding the Concept:
An autoimmune disorder is a condition where the immune system attacks the body's own tissues.

Step 2: Detailed Explanation:
In Myasthenia gravis, the body produces antibodies that block or destroy the acetylcholine receptors at the neuromuscular junction.
This prevents skeletal muscles from receiving nerve signals, leading to muscle weakness and fatigue.

Step 3: Final Answer:
The disorder is Myasthenia gravis.
