Put the following events of the neuromuscular junction in the order in which they occur.
1) Action potential is propagated in the sarcolemma.
2) Acetylcholine binds to ligand gated sodium channels.
3) Action potential arrives at the neuromuscular junction.
4) Vesicles full of acetylcholine are stored at the axon terminal.
5) Acetylcholine is released into the synaptic cleft.

Question

Quizplus · Accepted Answer

The correct sequence for the events at the neuromuscular junction starts with vesicles full of acetylcholine being stored at the axon terminal (4), followed by the arrival of an action potential at the neuromuscular junction (3). This triggers the release of acetylcholine into the synaptic cleft (5). Acetylcholine then binds to ligand-gated sodium channels on the muscle cell membrane (2), which leads to the propagation of an action potential in the sarcolemma (1).
