Rigor mortis

Explanation:

  • Rigor mortis is a postmortem change resulting in the stiffening of the body muscles.
  • This is due to chemical changes in their myofibrils.
  • Rigor mortis helps in estimating the time since death as well to ascertain if the body had been moved after death.
  • Its main cause is depletion of the cells energy molecule ATP.
  • ATP  separates actin-myosin bridges during muscle relaxation .
  • Without ATP cross-bridging locks muscles in place.
  • Eventually, decomposition breaks the bridges and muscles relax.
