Detailed explanation-1: -Rigor mortis is a chemical change resulting in a stiffening of the body’s muscles following death, resulting from changes in the myofribrils of the muscle tissues. Immediately following death, the body becomes limp and is easily flexed.

Detailed explanation-2: -Facial muscles and other small muscles are affected before larger muscles. Maximum stiffness is reached around 12-24 hours post mortem. Facial muscles are affected first, with the rigor then spreading to other parts of the body.

Detailed explanation-3: -Immediately after death, the muscles undergo primary relaxation, as mentioned above, which is followed by stiffening of muscles known as rigor mortis. With the onset of putrefaction, rigor mortis passes off, and secondary relaxation occurs.

Detailed explanation-4: -Rigor mortis (Latin: rigor “stiffness", and mortis “of death"), or postmortem rigidity, is the fourth stage of death. It is one of the recognizable signs of death, characterized by stiffening of the limbs of the corpse caused by chemical changes in the muscles postmortem (mainly calcium).
