Question 1

define the word rigors?

Accepted Answer

Shaking chills: Rigor is a shaking occurring during a high fever. It occurs because cytokines and prostaglandins are released as part of an immune response and increase the set point for body temperature in the hypothalamus.

Question 2

what is the definition or description of: rigors?

Accepted Answer

Rigors is the: Medical term for shaking chills, which is ofter associated with high fever as well.

Question 3

what is rigor mortis?

Accepted Answer

Contraction of the muscles: When someone dies the muscles tighten this  happens the muscles contract and become cross linked in the contracted state tightening takes about 12 hours to begin it is temperature dependent and eventually when decomposition occurs the rigor mortis is released in the body is very floppy  again.

Question 4

what causes rigor mortis?

Accepted Answer

Depletion of ATP: Depletion of ATP allows calcium to enter the muscles and activate the contractile proteins that cause stiffening of muscles.  It subsides when lysis of proteins starts as part of autolysis.

Question 5

what does it mean to have rigor mortis?

Accepted Answer

happens after death: Rigor mortis is the temporary stiffening of the muscles that occurs 2-6 hours after death and lasts 24-48 hours (depending on conditions).

Question 6

what is rigor fever?

Accepted Answer

Rigors: Rigors are uncontrollable shaking chills, often the precursor to major elevations of temperature and therefore high fevers.

Question 8

whay does a fever cause rigors?

Accepted Answer

Rigors: These uncontrollable shaking chills usually create fever through muscle activity, prompted by neurological impulses emanating from an area of the brain called the hypothalamus under the stimulus of pyrogens (fever inducing chemicals).  Rigors are felt to occur primarily in either patients with malaria or very severe bacterial infections with organisms released in mass into the blood stream.

Question 9

what is the reason for rigor mortis?

Accepted Answer

ATP depletion and: Calcium leakage.  The skeletal muscles continue using sugar to make ATP even after death, till the tissue runs out of sugar and atp. One of the consequences of ATP depletion is the formation of abnormal links between two components of muscle tissue, actin and myosin which causes muscle stiffening. Calcium leakage into muscle adds to that stiffening.

Question 10

how long does it take for rigor mortis to set in?

Accepted Answer

Varies: On average it commences after about three to four hours, reaches maximum stiffness after 12 hours, and gradually dissipates in approximately 48 to 60 hours. Time of onset is affected by activity before death, ambient temperature and ante-mortem diseases.
