Question

Quizplus · Accepted Answer

Rigor mortis is the condition in which the muscles of the body become stiff and rigid after death. This is caused by a lack of ATP in the muscles, which allows the myosin heads to bind to the actin filaments and form cross-bridges that cannot be released. The stiffness gradually disappears over a period of several hours to a few days as the muscles begin to decay.
