Place the following physiologic actions in the correct order in which they occur, from first to last.
- An action potential arrives at the axon terminal of a motor neuron.
- Synaptic vesicles release acetylcholine across the neuromuscular junction.
- Acetylcholine binds to receptors on the muscle fiber’s membrane causing electrical depolarization.
- Muscle contraction occurs.
- Acetylcholine in the neuromuscular junction is broken down by the enzyme acetylcholinesterase.
- Muscle contraction stops………………………………..$20
