The sliding filament model of contraction states that the sliding filament model of contraction states that during contraction, the thin myofilaments slide past the thick myofilaments so that the actin and myosin myofilaments overlap to a greater degree during contraction, the thin myofilaments slide past the thick myofilaments so that the actin and myosin myofilaments no longer overlap during contraction, the thin myofilaments slide past t tubules so that the z discs are overlapping during contraction, the thin myofilaments slide past the thick myofilaments so that calcium ions can be released from the sarcoplasmic reticulum submit
