Solution

acetylcholine binds to its receptor in the sarcolemma and triggers the opening of ligand gated cations channels.

Sodium and potassium ions do not diffuse in equal numbers through ligand-gated cation channels because, the inside surface of the sarcolemma is negatively charged compared to the outside surface. Sodium ions diffuse inward along favorable chemical and electrical gradients.
