The way in which actin and myosin interact in a sarcomere to bring muscle contraction. Introduction: During skeletal muscle contraction, a motor neuron stimulates the skeletal muscle fibers. The stimulation of skeletal muscle fibers ultimately causes the interaction between the myofilaments within the skeletal muscle fibers to produce a surface tension between the muscles. The first event in the contraction of the skeletal muscle is excitation of the muscle fiber by somatic motor neuron.
