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 has functions both in the peripheral nervous system (PNS) and in the central nervous system (CNS) as a neuromodulator. In the peripheral nervous system, acetylcholine activates muscles, and is a major neurotransmitter in the autonomic nervous system.cetylcholine 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.
