A patient with myasthenia gravis experiences muscle weakness. Which mechanism explains why acetylcholine esterase inhibitors improve muscle function in these patients?

💡 Explanation

Myasthenia gravis involves autoimmune destruction of acetylcholine receptors; therefore, acetylcholine esterase inhibitors increase the concentration of acetylcholine at the synapse by inhibiting its breakdown, because this compensates for the reduced number of functional receptors, rather than blocking receptors or affecting production.
