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 is when a body becomes stiff after someone dies. This happens because the body runs out of a special energy molecule called ATP, which helps muscles move. After death, the muscles can't relax, making the body feel hard. This stiffness usually starts a few hours after death and can last for about 12 hours.
