Test 4 List Questions Flashcards
List the effects that refrigeration has on a dead human body
1) Blood tends to remain very liquid; hypostasis to hemolysis is rapid
2) increase in intravascular blood discoloration into dependent body tissue eventually becoming extra vascular
3) refrigerated 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 decomp-hinders growth of bacteria
5) increases onset of algor mortis
6) freezer burn to surface tissue similar to to desiccation marks will occur during extended refrigeration
Antemortem or agonal desquamation is skin slip due to these conditions existing prior to death
1) Edema-most common-anasarca
2) I.V. Needle-infiltration
3) old and emaciated with unhealthy or degenerative epidermal tissue-diabetes
4) bandages carelessly pulled off
Temperature-one of the most important factors affecting bacterial growth
1) optimum-98 degrees F to 100 degrees F or body temperature
2) Minimum-32 degrees F
3) maximum 120 degrees F (which stops most decomposition)
Physical methods of reducing rigor mortis
1) flexing
2) extending
3) rotation
4) massaging
Characteristics of rigor mortis-muscle will become
1) shortened
2) stiffened
3) acid in reaction
4) loss of sensitivity to stimuli
The cardinal signs of decomposition
1) color
2) odor
3) purge
4) skin slip ( Desquamation )
5) accumulated gas
6) decomposition is the only positive sign of death
Causes of postmortem caloricity
1) heat is continuously produced after death by the oxidation of food products in tissues
2) the various methods of cooling the body, such as circulation, perspiration, and respiration have ceased, causing heat 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 ineffective disease
4) excessive muscular activity; an example would be the spasms produced by strychnine poisoning
Post Mortimer physical changes are brought about by
1) stoppage of blood circulation
2) gravitation of blood to the dependent parts of the body
3) environmental surface evaporation
