Question

Choose the correct sequence of events:

Action potential reaches synapse—Acetylcholine is released by motor neuron—Calcium ions enter motor neuron—Sodium ions flood into the muscle cell—Acetylcholine binds to gated ion channels on sarcolemma, transferring the action potential.


Action potential reaches synapse—Calcium ions enter motor neuron—Acetylcholine is released by motor neuron—Acetylcholine binds to gated ion channels on sarcolemma—Sodium ions flood into the muscle cell, transferring the action potential.

None of these.
Action potential reaches synapse—Calcium ions enter motor neuron—Acetylcholine is released by motor neuron—Acetylcholine binds to gated ion channels on sarcolemma—Sodium ions flood into the muscle cell, transferring the action potential.

Answer 1
