Answer:
Both conditions are caused by an inability of the body to produce adequate acetylcholine.
Explanation:
Botulism is a potentially fatal condition caused by the toxin of bacteria <em>Clostridium botulinum</em>. Early symptoms are weakness, slurred speech, blurred vision etc. It may lead to vomiting, abdominal swelling and respiratory failure if not treated. The toxin hinders the release of neurotransmitter acetylcholine due to which motor neurons are not able to send signals to muscle cells. Muscles are not able to function properly due to which paralysis occurs.
Myasthenia gravis is also a neuromuscular condition like botulism. But unlike botulism release of acetylcholine is not hindered here. The receptors for acetylcholine are destroyed or altered by body's own immune system. Acetylcholine despite being present is not able to relay the signal which leads to muscle weakness. Symptoms are almost similar to those of botulism.
