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.
Acetylcholine is a neurotransmitterâa chemical messenger that helps carry signals across a nerve synapse. It was the first neurotransmitter to be discovered, and has been heavily studied. It is also the most abundant neurotransmitter and is present in both the central nervous system and peripheral nervous system.cetylcholine works together with the neurotransmitter dopamine to enable smooth movements. When there is an imbalance between acetylcholine and dopamine, movements can be shaky and uneven, a hallmark of Parkinsonâs disease. References: 1  Alzheimerâs disease medication fact sheet.
