Rigor Mortis

The process that causes the muscles in the body to stiffen resulting in rigidity after death is called

• algor mortis

• rigor mortis

• livor mortis

Estimate the approximate time of death for the following situation:

A body was found with no evidence of rigor.

• 2 - 6 Hours

• 8 Hours

• Less than 2 Hours

• More than 10 Hours

Maximum rigor mortis occurs

• between 2-4 hours

• 2-6 hours after death

• 12 hours after death

• 48 hours after death

Rigor mortis starts at the feet and moves up the body.

• less than 2 hours or more than 24 hours

• less than 2 hours or more than 36 hours

What is the biochemical basis of rigor mortis?
