Rigor mortis, the stiffening of a body several hours after death, arises from a combination of two of the oldest definitions of death â cessation of the heartbeat and cessation of breathing. Once either of these essential functions stops, the cells of the body lose their oxygen supply and can no longer perform aerobic respiration. Immediately after death, the muscles of the body contract in the same manner as they do when the person is alive. Muscle is formed of bundles of long and narrow cells that can span the entire muscleâs length.
