Rigor mortis
Rigor mortis (Latin: rigor "stiffness", mortis "of death") is one of the recognizable signs of death, caused by chemical changes in the muscles after death, causing the limbs of the corpse to stiffen. Rigor mortis occurs three to four hours after death.
Physiology
After death, respiration in organisms ceases to occur, depleting the corpse of oxygen used in the making of adenosine triphosphate (ATP). When oxygen is no longer present the body may continue to produce ATP via anaerobic glycolysis. When the body's glycogen is depleted, the body's ATP concentration diminishes and the body enters rigor mortis. ATP is required to cause separation of the cross-bridges during relaxation. Additionally, calcium enters the cytosol after death. Calcium is released into the cytosol due to the deterioration of the sarcoplasmic reticulum. Also, additional calcium enters the cytosol from the extracellular fluid due to the breakdown of the sarcolemma. The calcium activates the formation of myosin-actin cross-bridging. Once calcium is introduced into the cytosol, it binds to the troponin of thin filaments, which causes the troponin-tropomyosin complex to change shape and allow the myosin heads to bind to the active sites of actin proteins. In rigor mortis myosin heads continue binding with the active sites of actin proteins via adenosine diphosphate (ADP) and the muscle is unable to relax until further enzyme activity degrades the complex.

Rigor Mortis (band)
Rigor Mortis is a thrash/speed metal band that formed in 1983 in the Dallas-Fort Worth, Texas metroplex. Two schoolmates Harden Harrison (drums) and Casey Orr (bass) formed the band when they met Mike Scaccia (guitar). The three young men shared an interest in horror/gore films and very heavy music. With Bruce Corbitt on vocals they created some of the heaviest thrash metal at the time often flirting with death metal. They were also one of the only major thrash bands from Texas and virtually created the underground metal scene there. The band was signed by Capitol Records in 1987.
In 2005, the original lineup reunited and performed at Ozzfest 2008 in Texas. In 2009, Rigor Mortis played in Germany at the Keep It True Festival.
Rigor Mortis recently recorded their first album with the original lineup in 25 years. The album will be called "Slaves To The Grave" and it will be released on October 7, 2014.
Mike Scaccia also played guitar with industrial metal band Ministry, Revolting Cocks, Lard, and others.
