Excitation-contraction coupling in skeletal muscle fibers involves the release of calcium ions to enable muscle contraction triggered by action potentials.
Excitation-contraction coupling is the link between the action potential and muscle contraction in skeletal muscle fibers. It involves the release of calcium ions that interact with troponin and tropomyosin to enable muscle contraction. The process starts with the arrival of an action potential at the neuromuscular junction.
