Term
| Necropsies help to determine? |
|
Definition
| Cause of death and chronicle a disease progression |
|
|
Term
| Postmortem changes include? |
|
Definition
Umbrella term: postmortem autolysis
Autolysis & putrefaction |
|
|
Term
|
Definition
| postmortem changes due to the release of proteolytic enzymes from proliferating bacteria |
|
|
Term
|
Definition
| postmortem changes due to proteolytic lysosomal enzymes being released from cells as they die |
|
|
Term
|
Definition
| Contraction and stiffening of muscles post-mortem. Begins 1-6 hours after and passes in 36-48 hours. If temp is high putrefaction will completely displace rigor within 9-12 hours post-mortem |

|
Term
| How can one tell if an animal is in rigor mortis? |
|
Definition
| You cannot move their muscles because they are tense. It is impossible. If you can move them but are stiff this is past the period of rigor mortis. Limbs do not become limber again. |
|
|
Term
| Livor mortis (hypostatic congestion) |
|
Definition
settling of blood to the down side of the animal body due to gravity. Gravitational setting of blood and body fluids result in intense dark red coloration of organs and tissue a the "down" side of the cadaver. THIS DOES NOT OCCUR IN INTESTINES. Most obvious in light colored tissues like the brain and the lungs.

Term
|
Definition
pink to red coloration that is imparted on tissues due to the lysing of RBCs. Evident on inner surfaces of large arteries and outer surfaces of light colored organs

Term
|
Definition
tissues become discolored due to the action of bacteria on hemoglobin which forms a gas called HYDROGEN SULFIDE.
Hydrogen sulfide combines with the iron to form iron sulfide which causes the changes in pigmentation to the tissues.
Black tissue = anaerobic environment
Green = aerobic environment

| What causes red intestines? |
|
Definition
| Congestion, hemorrhage, inflammation or hemoglobin inhibition |

|
Term
|
Definition
| increase in amount of blood in an organ (or part of an organ) within the blood vessels |
|
|
Term
|
Definition
| this doesn't need an explanation because it's a vascular/cellular response of body to injury |

|
|
Term
|
Definition
