FINAL ROUND Question
Which of the following describes the general sequence of events at a neuromuscular
synapse?
1 – Receptor binding may lead to the generation of an action potential in the axon (if
the postsynaptic cell is a neuron) or sarcolemma (if the postsynaptic cell is a skeletal
muscle fiber).
2 – Arrival of the action potential at the terminal bouton triggers release of
neurotransmitter from secretory vesicles, through exocytosis at the presynaptic
membrane.
3 – The neurotransmitter molecules are either enzymatically broken down or
reabsorbed.
4 – Receptor binding results in a change in the permeability of the postsynaptic cell
membrane.
