Myasthenia gravis is an autoimmune disease that results in the destruction of acetylcholine (ACh) receptors. Its symptoms include systemic muscle weakness plus swallowing and speech difficulties. Discuss how the lack of ACh receptors would cause these effects. (5 points) Be sure to use your own words. Do not use abbreviations. Include a citation for the reference (text or other sources) you used in formulating your response. If you do not include a citation, you will lose 2 points for this question.

Step 1
Acetylcholine is a neurotransmitter that plays a crucial role in the communication between nerves and muscles. The destruction of ACh receptors impairs the transmission of nerve impulses to the muscles, resulting in muscle weakness and fatigue. The lack of ACh Show more…

Myasthenia gravis is an autoimmune disease that initially presents with muscle weakness and can progress to complete impairment of muscle movement. The diagram compares a healthy individual with an individual suffering from this disease. Which statement best explains what happens to bring about this disease? a. The body produces antibodies against nerve cells, which prevents the nerve cells from releasing acetylcholine during signal transmissions to muscle. b. The body produces antibodies against acetylcholine, which prevents acetylcholine from transmitting signals from nerves to muscle. c. The body produces antibodies against receptors in muscle, which prevents acetylcholine from binding and completing nerve signal transmission. d. The body produces antibodies against acetylcholine, which prevents acetylcholine from breaking down after signal transmission is complete.
Assertion: Myasthenia gravis is autoimmune disorder. Reason: It results due to antibodies are formed that block our own nicotinic acetylcholine receptor at neuromuscular junction.
