Full Definition of rigor mortis

  1. :  temporary rigidity of muscles occurring after death

Did You Know?

Rigor mortis, which translates from Latin as "stiffness of death", sets in quickly and usually ends three or four days after death. The condition results from a lack of certain chemicals in the muscles; it may be affected by muscular activity before death as well as the external temperature. Mystery writers frequently make use of rigor mortis as a means by which the detective or the examiner can determine the time of the victim's death, which often turns out to be all-important in solving the case.
