What is a strict mortis?

Rigor Mortis is a state that begins to evolve in the body after death. In principle, it is by the strictness of the Mortis to start a process where the muscles in the body begin to solidify. In most situations, the corpse will begin to undergo a process of strictness Mortis about three hours after death, and will continue to experience muscle stiffening anywhere from thirty -six to seventy -two hours.

Strict mortis takes place because of the fact that once a living being is dead, there is no longer a constant flow of adenosine triphosphate or, etc. ATP needs to help relax the muscles from the state of contraction caused by the presence of calcium ions that flow into the muscles and act as a bridge or connection between actin and myosin, which is present in the muscle fiber. Without ATP, which starts the release of this connection, the muscles continue to download, so the dead body will be rigid. It is only then in the muscles that they begin to decompose that the binding between actin and myosin fibers breaks down and the muscles in the body begin to lose rigidity.

The reality of the strictness of Mortis often led to situations where the corpse would be monitored on the first night after death. The purpose of the event was commonly referred to as "seating with the body", preventing the muscles from working at the work of the corpse on positions that were not suitable for funeral traditions. Several people would often stay with the corpse all night and straighten the limbs or reduce the body back to a susceptible position if the muscles reinforcement caused the knee or elbow bending, or the corpse bends at the waist and appears to sit down.

The state of the strictness of mortis can also help medical investigators and experts in the area of ​​enforcement of the right to determine the approximate period of deadly the individual did not separate in the care facility, or while the loved ones were nearby. Along with other factors, the degree of muscle stiffening, which is present during the autopsy procedures, reduces the extent to death, providing valuable traces when a foul is suspected.
