The contraction of skeletal muscle includes ultrastructural and biochemical events. Ultrastructural events leads with stimuli excitation of T-system followed by crossbridge formation (myosin and actin filaments involved) and the cross bridge breakage. The biochemical events explain that stimuti leads to neurotransmitter secretion, excitation of T-system and release of
