A patient with myasthenia gravis is experiencing worsening muscle weakness. Which neurotransmitter's receptor is most commonly affected in this condition?
Dopamine
Acetylcholine
Norepinephrine
Serotonin
In myasthenia gravis, the body's immune system produces antibodies that block or destroy many of the muscle receptor sites for acetylcholine, a neurotransmitter. This reduces the ability of muscles to respond to nerve signals, causing muscle weakness. Other neurotransmitters like dopamine and serotonin are not primarily involved in this condition.
