Arrаnge the аctivities аt the neurоmuscular junctiоn in the оrder in which they occur. Calcium channels open and Ca ions diffuse into axonic end bulb. Acetylcholine diffuses across the synaptic cleft. Sodium (Na) channels open in motor end plate. Acetylcholine binds to receptors on the motor endplate. An action potential arrives at the axonic end bulb. Muscle fiber action potential is produced. Acetylcholine is released from synaptic vesicles within the axonic end bulb.
