Detailed explanation-1: -Rigor mortis is the post-mortem stiffening of muscles caused by the depletion of adenosine triphosphate (ATP) from the muscles, which is necessary for the breakdown of actin-myosin filaments in the muscle fibers. Actin and myosin are components of the muscle fiber and form a covalent bond during contraction.

Detailed explanation-2: -Rigor mortis (postmortem rigidity) is the stiffening of the muscles of the corpse due to the depletion of adenosine triphosphate (ATP) after death with the subsequent build-up of lactate in muscle tissue resulting in an inability to release the actin-myosin bond.

Detailed explanation-3: -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-4: -Changes in the muscles: 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-5: -Rigor mortis is one of the most well-known taphonomic alterations, and it is the process by which the body’s muscles stiffen, resulting in rigidity, as a result of a variety of chemical changes in the muscle structure. Stage I: Autolysis. Stage II: Bloat. Stage III: Active Decay. More items
