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.nside the brain acetylcholine functions as a neuromodulator âa chemical that alters the way other brain structures process information rather than a chemical used to transmit information from point to point. The brain contains a number of cholinergic areas, each with distinct functions.
