List Questions Exam 4

Question 1

1. Blood tends to remain very liquid; hypostasis to hemolysis is rapid.
2. Increase in intravascualr blood discoloration into dependent body tissue eventually becomming extravascular.
3. Refridgerated bodies often appear embalmed because of cold stiffening and red blood discoloration that resemble active dye in arterial fluid.
4. Slows the onset of rigor mortis and decomposition- hinders the growth of bacteria.
5. Increases the onset of algor mortis.
6. Freezer burn to surface tissue similar to desiccation marks will occur during extended refridgeration.

Answer 1

List The Effect That Refridgeration Has on a Dead Human Body.

Question 2

1. Color
2. Odor
3. Purge
4. Skin Slip (Desquamation)
5. Accumulated Gases
6. Note: Decomposition is the only positive sign of decomposition.

Answer 2

The Cardinal Signs of Decomposition

Question 3

1. Edema - Most common - Anasarca
2. I.V. needle - Infiltration
3. Old and emaciated until unhealthy or degenerative epidermal tissue - diabetes.
4. Bandages carelessly pulled off.

Answer 3

Antemortem or Agonal Desquamation is skin slip due to conditions existing prior to death.

Question 4

1. Flexing
2. Extending
3. Rotating
4. Massaging

Answer 4

Physical Means of reducing rigor mortis.

Question 5

1. Optimum - 98^oF to 100^oF or body temperature.
2. Minimum- 32^oF
3. Maximum- 120^oF (which stops decomposition).

Answer 5

Temperature- One of the most important factors affecting bacterial growth.

Question 6

1. Stoppage of blood circulation.
2. Gravitation of blood to the dependent parts of the body.
3. Environmental surface evaporation.

Answer 6

Postmortem Physical Changes Are Brought About by The:

Question 7

1. Heat is continually produced after death by the oxidation of the food products in tissues.
2. The various methods of cooling the body, such as circulation, perspiration, and respiration have ceased, causing head to accumulate in tissues.
3. The activity of bacteria prior to death causing energy and heat to build up in tissues- septicemia or any febrile infective disease.
4. Excessive muscular activity; an example would be the spasms produced by strychnine poisoning.

Answer 7

List The Causes of Postmortem Caloricity

Question 8

1. Shortened
2. Stiffened
3. Acid in reaction
4. Loss of sensitivity to stimuli

Answer 8

Characteristics of rigor mortis- muscles will become:
