Quizplus · Accepted Answer

The binding of acetylcholine to its receptor at the neuromuscular junction causes the opening of a channel for both Na+ and K+ ions, allowing for depolarization of the muscle cell membrane and activation of the muscle contraction process. This is commonly referred to as the nicotinic acetylcholine receptor (nAChR) and is composed of five subunits, including two alpha subunits that are responsible for binding acetylcholine.
