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.
