rigor

 [rig´or, ri´gor]
1. a chill; rigidity.
2. strict discipline or scrupulous adherence to a given set of standards.
rigor mor´tis the stiffening of a dead body accompanying depletion of adenosine triphosphate in the muscle fibers.

rig·or mor·'tis

stiffening of the body, 1-7 hours after death, from hardening of the muscular tissues as a consequence of the coagulation of the myosinogen and paramyosinogen; it disappears after 1-6 days or when decomposition begins.

rigor mortis

(môr′tĭs)
n.
Muscular stiffening following death.

rigor mortis

[môr′tis]
the rigid stiffening of skeletal and cardiac muscle shortly after death.
Stiffness of a cadaver. The following are crude approximations of the time of death, based on temperature and presence/absence of rigor
warm and flaccid < 3 hours
warm and stiff 3-8 hours
cold and stiff 8-36 hours
cold and flaccid > 36 hours

rigor mortis

Post-mortem corporal rigidity, stiff stiffness Pathology Board-like contraction of skeletal muscles that first appears in jaw and other short muscles–eg, of hand, 2-4 hrs after death; RM later appears on the trunk and extremities, peaks at 24-48 hrs; it disappears in the same order as it developed. Cf Livor mortis.

rig·or mor·tis

(rī'gōr mōr'tis)
Stiffening of the body, from 1-7 hours after death, from hardening of the muscular tissues in consequence of the coagulation of the myosinogen and paramyosinogen; it disappears after 1-6 days, or when decomposition begins.
Synonym(s): postmortem rigidity.

rigor mortis

The stiffening of muscles which occurs after death as a result of the loss of ATP so that the cross bridges cannot disconnect from actin. Rigor usually starts about 3 or 4 hours after death and is usually complete in about 12 hours. It may start much earlier, sometimes almost immediately, if the subject was engaged in strenuous activity or was fevered or suffering convulsions before death. It passes off as enzymes break down and soften the muscles over the course of the next 2 or 3 days.

rigor mortis

the temporary stiffening of a body after death.

rig·or mor·tis

(rig'ŏr mōr'tis)
Stiffening of the body, from 1-7 hours after death, due to hardening of the muscular tissues in consequence of the coagulation of the myosinogen and paramyosinogen.
Synonym(s): postmortem rigidity.

rigor mortis,

n the stiffening of skeletal and cardiac muscle shortly after death.

rigor

a subjective sensation of feeling cold, accompanied by muscle tremor, characteristic of the increment stage of fever. Because of its subjectivity it is not a term that can be used in animal medicine.

rigor complexes
formed when actin and myosin bond together strongly in the absence of ATP; occurs in rigor mortis.
rigor mortis
the stiffening of a dead body accompanying depletion of adenosine triphosphate in the muscle fibers.
