Term
| post-mortem changes:rigor mortis |
|
Definition
| general stiffening of the muscles that begins 1-9 hours after death. Muscle contraction is due to the loss of ATP. ATP can be generated from glycogen stores so well nourished animals will develop rigor later. Warm temperatures develop rigor earlier. Occurs in a defined order: head->heart->diaphragm->limbs. Rigor is lost 12-30 hours later due to autolysis. |

Term
| post mortem changes: blood changes |
|
Definition
blood pools due to gravity.
blood clots: post-mortem clots and chicken fat clots...clots fill the vessels and conform to their shape. |

Definition
autolysis- enzymatic breakdown and liquefaction of tissues
Putrefaction- breakdown of organic matter by saprophytic microbes. This also involves:
1.gas production
2. putrefactive odors
3. discoloration - dark red/blue(anoxic blood), blood pigment release, Iron sulphide release (green) |
