Rigor mortis;
|
Stiffness of the muscles. Rigidity lasting for varying periods of time. It begins in the involuntary muscles & w/in 2-4 hrs it affects the vountary muscles (develops due to ATP depletion in the muscles of the dead subject)
|
|
|
Postmortem changes:
|
Rigor mortis, Livor mortis, Algor mortis, Intravascular clotting, Autolysis, Putrefaction.
|
|
|
Livor mortis:
|
Also called mostmortem lividity. It is a reddish-blue discoloration of the body, resulting from gravitational pooling of blood, & cooling.
|
|
|
Algor mortis:
|
(rate of the cooling) Inevitable cooling of a dead subject as the body temp. approaches the environmental temp. (the rate of cooling depends on the temp. before & after death.
|
|
|
Intravascular clotting:
|
Results in clots that are not adherent to the lining of the blood vessels & heart.
|
|
|
Autolysis:
|
Digestion of tissues from released substances, such as enqymes from lysosomes.
Organs may be swollen & spongy in appearance. |
|
|
Putrefaction:
|
breaking down of organic matter; decomposition or rotting.
|
|
|
Intracellular infiltrations are also known as -
|
cellular accumulations
|
|
|
Abnormal accumulations of substances the are normally present can occur in the cyto plasm , lypsosomes or the nucleus if?
|
1. Substance is produced in excess or at an increased rate.
2.An endogenous substance is not effectively catabolized. 3. Harmful extogenous materials accumulate by inhalation, ingestion or infection. |
|
|
Substances of Intracellular infiltrations are what 3 groups?
|
1. Normal body substances (protiens, carbohydrates, fat, nutrients etc..)
2. Abnormal endogenous products 3. Exogenous products |
|
|
Cellular swelling the most common degenerative change is caused by -
|
the shift of extracellular water into the cells.
|
|
|
In hypoxic injury -
|
Movement of fluid & ions into the cell is associated with acute failure of metabolism & loss of ATP production.
|
|
|
Is cellular swelling reversible?
|
Yes, if O2 is given in a timely manner.
