A Deficiency of Acetylcholine Receptors Leads to Muscle Paralysis in Myasthenia

Question

A deficiency of acetylcholine receptors leads to muscle paralysis in myasthenia gravis.

Accepted Answer

Myasthenia gravis is an autoimmune disorder where the body produces antibodies that attack acetylcholine receptors on muscle cells, leading to a decrease in the number of functional receptors. This results in muscle weakness and paralysis. Thus, a deficiency of acetylcholine receptors is a key feature of myasthenia gravis.
