Rigor mortis refers to the process where a body becomes stiff after death. This occurs because the body runs out of adenosine triphosphate (ATP), which is essential for muscle relaxation. As ATP levels drop, the muscles become rigid and cannot contract. This stiffening usually starts a few hours post-mortem and can last for up to 12 hours, making it an important concept in both biology and forensic science.
Rigor mortis refers to the stiffening of muscles that occurs after death, which is an important aspect of the post-mortem process. This phenomenon happens due to the depletion of adenosine triphosphate (ATP) in the muscles, leading to a state where they can no longer relax. Typically, rigor mortis begins a few hours after death and can last for up to 12 hours, providing valuable information for forensic science in determining the time of death.
