What is the average duration of rigor mortis?

• A. 12-24 hours
• B. 24-48 hours
• C. 48-72 hours
• D. 72-96 hours

Answer: (B)

The average duration of rigor mortis is typically 24-48 hours following death. This postmortem condition results from the biochemical processes that occur after the body ceases to function. Rigor mortis begins within a few hours after death, generally starting in the smaller muscles first and gradually progressing to larger muscle groups. As time progresses, the stiffness will peak and then gradually diminish as the muscle tissues break down and begin to decompose. Understanding this timeframe is crucial in various aspects of mortuary science, including embalming, as it helps professionals assess the state of the body and determine appropriate procedures to take. The other durations mentioned do not accurately reflect the established timeframe for rigor mortis, as it typically resolves within the 24-48 hour window. Beyond this period, the body will enter a phase of decomposition wherein rigor mortis is no longer a factor. Therefore, recognizing the average duration of rigor mortis at 24-48 hours is significant in embalming practice for the timing of intervention and preservation techniques.
