Detailed explanation-1: -Rigor mortis is a postmortem change resulting in the stiffening of the body muscles 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.

Detailed explanation-2: -Rigor mortis, which translates from Latin as “stiffness of death", sets in quickly and usually ends three or four days after death. The condition results from a lack of certain chemicals in the muscles; it may be affected by muscular activity before death as well as the external temperature.

Detailed explanation-3: -Rigor Mortis or postmortem rigidity is the stiffness of the muscles and joints of the body post-death of a person, usually lasting between one and four days. It is the third stage and a noticeable sign of death, which is due to chemical changes in the muscles which brings about a stiffening of the muscles of limbs.

Detailed explanation-4: -Rigor mortis appears approximately 2 hours after death in the muscles of the face, progresses to the limbs over the next few hours, completing between 6 to 8 hours after death. [10] Rigor mortis then stays for another 12 hours (till 24 hours after death) and then disappears.

Detailed explanation-5: -Rigor mortis refers to the stiffness of the body after the death of a person. Rigor mortis is because of the biochemical change in the muscles which occurs a few hours after the death, although the time of its occurrence after the death totally depends on the ambient temperature.
