The function of Ca 2+ in skeletal muscle contraction. Concept introduction: The first event in the contraction of the skeletal muscle is excitation of the muscle fiber by somatic motor neuron. The second physiological event after the muscle fiber excitation is “excitation-contracting coupling”. It is an event that involves T-tubules, sarcolemma and sarcoplasmic reticulum. The next event involves binding of calcium ions and cross-bridge cycling.
