About.com Chemistry notes that the time it takes for the onset of rigor mortis to occur depends on the environmental conditions at the time of death, as this affects the temperature of the body. About.com explains that colder temperatures speed up the rigor mortis process. The face is usually the first to set, followed by the body.
Rigor mortis typically lasts up to 72 hours, according to About.com. Afterwards, the joints unlock, and the muscles once again start to relax as a result of the body decaying.Learn more about Human Anatomy
Rigor mortis typically sets in three to six hours after death. However, rigor mortis sets in more quickly in smaller animals than in large, so a very small dog might stiffen within a few hours.Full Answer >
The six stages of rigor mortis in humans include absent, minimal, moderate, advanced, complete and passed, according to the Medicolegal Death Investigators' training manual on Education Portal. When rigor mortis occurs, the body's muscles harden after death in a gradual process.Full Answer >
According to the Encyclopedia of Death and Dying, two to eight hours after death, the body stops producing adenosine triphosphate and muscles begin to stiffen. This occurs in part because oxygen no longer circulates. Other post-mortem biochemical changes also cause abnormal contraction of the muscles because the body is unable to remove the by-product lactose from the muscles to prevent them from stiffening.Full Answer >
Depending on the type of apple, it can turn brown almost instantly after being cut or take up to several hours. The oxidation process causes the apple to turn brown; oxygen present in the air reacts with the enzymes on the flesh of the apple.Full Answer >
