what isthe physiological & pathological explanation for rigor mortis?

The body does not break OH MY GOD!!!! The peak it does not have a peak it depends on the body and cause of death. Rigor lasts 48 to 72 hours. The body by the way starts decomposition as soon as cellular death happens.
You can very much relieve rigor. FLEX, ROTATE, MASSAGE, BEND. It reverses it self at 72 hour point why because the body lets go of its intravascular resistance it is in the interstitial
tissue spaces. That is a very basic explanation. Please do not think the body will break. The bones will just like if you break anyones bones if you try hard enough. I hope you don't think I am being mean or anything. That is not my intent.

This is an anatomy question that has a chemistry background, and without understanding the chemistry behind it, there is no possible way for you to understand what is going on. Go online and look up the chemical processes of how muscles flex! The ATP is no longer being supplied, no energy no moving.

The livor motis is (2 - 3+.
