What is the role of acetylcholine in a skeletal muscle contraction? Your answer: It binds to receptors and initiates a change in ion permeability that resutls in the contraction of the muscle cell. 3. Describe the process of excitation-contraction coupling in skeletal muscle fibers. Your answer: This is the entire process of the neuromuscular juntion leading to the end-plate potential.
Inhibition of Acetylcholinesterase at the Neuromuscular Junction I. Background Acetylcholine is the neurotransmitter used at the neuromuscular junction to generate muscle contractions. Acetylcholine (ACh) is released when an action potential reaches the axon terminus of a motor neuron.his Ca 2+ triggers the movement of ACh filled vesicles to the pre-synaptic nerve cell membrane and the exocytotic release of ACh. ACh then diffuses across the neuromuscular junction and binds to its receptor on the post-synaptic cell membrane (in this case, the plasma membrane of the muscle cell).
