Rigor mortis sets in after the death of humans and other animals because the supply of ATP decreases to the point at which calcium can no longer be removed from the cell. At this point, the myosin molecules attach to the thin filament. The muscles stiffen, and limbs cannot be moved. Why and for how long does the muscle then remain in this continuously contracted state?
