Muscles contraction flowchart AP on somatic motor neuron Release of ACh into the synaptic clef Ach will bind to the Ach receptors which are located on the sarcolemma/motor endplate Sodium enters the cytosol There is an AP on the sarcolemma AP will travel down the t-tubule The SR releases Ca+2 Ca+2 binds to the troponin The tropomyosin will uncover the myosin binding sites on the actin ATP forms cross bridges between the actin and myosin Power strokes happen (the thick filaments pulls the thin filaments in) Cross bridges break thanks to ATP ATP hydrolysis and activates (Cocks) the myosin head More cross bridges will form The thin and thick filaments slide closer together (sliding filament mechanism)...
