rigor mortis?


Question:
what is it??!

Answers:
the stiffening of the body after death. hence the term a "stiff" for a dead body. "Rigor mortis is a recognizable sign of death (Latin "mortis") that is caused by a chemical change in the muscles, causing the limbs of the corpse to become stiff (Latin "rigor") and difficult to move or manipulate. Assuming mild temperatures, rigor usually sets in about 3-4 hours after clinical death, with full rigor being in effect at about 12 hours, and eventually subsiding to relaxation at about 36 hours. Times for the onset of rigor mortis can vary from a few minutes to several hours depending on the temperature of the environment in which the body is found"

all the answers below are right so i will just step to the side
Rigor mortis refers to the state of a body after death, in which the muscles become stiff. It commences after around 3 hours, reaching maximum stiffness after 12 hours, and gradually dissipates until approximately 72 hours after death. Rigor mortis occurs due to changes in the physiology of muscles when aerobic respiration ceases.

keep on breathing!
also, it sets in faster if the person was physically exerting him or her self before death because the speed of rigor mortis setting in has to do with the amount of adenosine triphosphate (ATP) in the muscles at the time of death in addition to factors like climate.
when the body becomes stiff after a person passes away
When you die your body stiffens. Rigor Mortis is just Latin.
