Acetylcholine is the neurotransmitter used at the neuromuscular junction âin other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles.
The action potential travels to the axon terminal, releasing acetylcholine into the synaptic cleft. 3. Acetylcholine binds a receptor on the skeletal muscle cell and generates an action potential, increasing Ca++ release from the sarcoplasmic reticulum.4. Ca++ initiates contraction, resulting in shortening of the muscle cell and, consequently, movement.he action potential travels to the axon terminal, releasing acetylcholine into the synaptic cleft. 3.
