Rigor mortis typically begins how many hours after death?

Rigor mortis typically begins between 2 to 6 hours after death, which is why this answer is correct. After death, the muscles in the body begin to stiffen due to biochemical changes, primarily the depletion of ATP (adenosine triphosphate), which is necessary for muscle relaxation. The onset of rigor mortis can vary based on factors such as the individual's physical condition, environmental temperature, and the circumstances surrounding the death.

Understanding that rigor mortis has a specific timeline is crucial for various fields, including forensics and healthcare, as it can help determine the time of death. The process usually peaks around 12 hours postmortem and can last up to 24 to 36 hours before the muscles start to relax again as decomposition progresses.
