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: -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-3: -Rigor mortis refers to the changes in muscle tissue that occur after death. The muscles become very stiff or rigid and are frozen in a contracted state.
Detailed explanation-4: -Rigor mortis is the post mortem stiffening/ rigidity of the body. It results from a decrease in levels of adenosinetriphosphate (ATP) beyond critical levels. When a person dies, calcium ions flood muscle fibers due to the loss of integrity of the muscle cells.
