quiz 6

Question 1

adipocere

Answer 1

“grave wax”
the final product of fat decomposition
chemical change

Question 2

agonal period

Answer 2

the period occurring just before death
Length of period cannot be measured in defined parameters
person is said to be moribund, or actively dying during this state

Question 3

algor mortis

Answer 3

cooling of the body to the temperature of the surrounding environment

Question 4

biological death

Answer 4

the irreversible phase of somatic death and represents the cessation of simple body processes. The organs in the body no longer function

Question 5

clinical death

Answer 5

when spontaneous respiration and heartbeat irreversibly cease

Question 6

clostridium perfringens

Answer 6

an anaerobic, spore forming bacillus responsible for true tissue gas

Question 7

death rattle

Answer 7

a gurgling, or rattling in the throat caused by the accumulation of mucus and exacerbated by loss of the cough

Question 8

desquamation

Answer 8

aka skin slip, is a sign of decomposition

Question 9

death struggle

Answer 9

presents as reflexive twitching of the muscles, marking the final efforts to sustain life

Question 10

hypostasis

Answer 10

gravitation of blood and body fluids to depended areas of the body
postmortem physical change

Question 11

imbibition

Answer 11

the ability of the cells to draw moisture from the surrounding area into themselves

Question 12

postmortem caloricity

Answer 12

temporary rise in body temperature after death

Question 13

postmortem cellular death

Answer 13

the process during which individual cells die. It may take a matter of hours depending on numerous variables

Question 14

postmortem chemical changes

Answer 14

postmortem caloricity, postmortem stain, decomposition, change in pH

Question 15

postmortem stain

Answer 15

extravascular color change brought about by hemolysis; liberated hematin seeps through capillary walls and into the body tissues; cannot be removed by arterial injection
chemical change

Question 16

purge

Answer 16

sign of decomposition, fluid is forced from the orifices of the body

Question 17

rigor mortis

Answer 17

creates extravascular resistance; body positioning and feature settling challenges; tissue distension during arterial injection; increases preservative demand…pH changes affect chemical reaction of embalming solution… false sign of preservation

Question 18

somatic death

Answer 18

is defined as death of the entire body
actually a process and not a moment in time
is realized once the body loses ability to sustain physiologic and metabolic activity

Question 19

body transfer board

Answer 19

Aka smooth mover
These thin, smooth, flat polyethylene boards, are strong, non absorbent, and easily cleaned

Question 20

brain death

Answer 20

occurs in a sequence of events that are a function of time without oxygen. The first part of the brain to die, usually in 5-6 minutes is the cerebral cortex. Next the midbrain dies, followed by the brain stem

Question 21

postmortem physical changes

Answer 21

algor mortis, hypostasis, livor mortis, dehydration, increased viscosity of blood, endogenous invasion of microorganisms

Question 22

calvarium clamp

Answer 22

holds skull bones in place after autopsy

Question 23

centrifugal pump

Answer 23

Potential pressure
Actual pressure
Differential

Question 24

electric spatula

Answer 24

used to draw excess swelling and to displace moisture under the skin
always keep moving and use lots of massage cream

Question 25

needle injector

Answer 25

used to insert a “barb” into the mandible and maxilla to hold the jaw closed
