Types of rigor mortis

Answer 1

Whatever the subject did before it died xP No really it causes the body to lock into the exact position it was in before it died. The muscles tighten up so much that it does not allow the body to move.

Answer 2

Rigor Mortis occurs within 72 hours after death. You get more calcium in your bones. Rigor Mortis can tense up your muscles because your muscles do not have energy (and you obviously do not have energy because you are dead).

You see, muscles contract (harden) after death because there is no energy. This means that Myosin (a thick muscle filament) can grab Actin (a thin muscle filament) and pull it (that is how you flex your muscles) and therefore the muscle will stiffen.

Answer 3

Rigor Mortis is the name used to describe the stiffening of the body muscles after death. It usually begins 2-6 hours after death.

There are not different 'types' of rigor mortis, however it does occur in different stages. The muscles of the jaw, eyelids and neck will be the first areas to show signs of rigor mortis. Over the next 4-6 hours, rigor mortis will spread to other muscles, including internal organs such as the heart.
