Rigor mortis
Rigor mortis is the stiffening of the body which occurs fairly soon after death (30 minutes to two hours) and disappears once putrefaction begins (after 2 to 4 days).
Cause of rigor mortis
Rigor mortis is caused by biochemical changes in muscle fibres. Molecular bridges form between actin and myosin proteins. These are broken down by autolysis at putrefaction.
The muscles of a cadaver stiffen rapidly and become rigid. © Google/Noobformua, Youtube.
