a) Algor mortis
b) Rigor mortis
c) Livor mortis
d) Putrefaction

Answer 2

Answer:
a) Algor mortis

Rationale:
The gradual reduction of body temperature after death is known as algor mortis.

Question 3

Question 3:
What causes the purple discoloration of the skin in dependent tissues, such as the lower parts of the body, after death?
a) Rigor mortis
b) Algor mortis
c) Livor mortis
d) Putrefaction

Answer 3

Answer:
c) Livor mortis

Rationale:
Livor mortis is responsible for the purple discoloration of dependent tissues due to the settling of blood.

Question 4

Question 4:
What causes muscle stiffening, known as rigor mortis, to develop after death?
a) Accumulation of acidic compounds in the muscles
b) Cooling of the body
c) Putrefaction
d) Loss of blood pressure

Answer 4

Answer:
a) Accumulation of acidic compounds in the muscles

Rationale:
Rigor mortis develops due to the accumulation of acidic compounds in the muscles, interfering with the detachment of myosin from actin.

Question 5

Question 5:
When do signs of putrefaction become generally obvious after death?
a) Within minutes
b) Within 6 hours
c) About 24 to 48 hours
d) Within 12 to 14 hours

Answer 5

Answer:
c) About 24 to 48 hours

Rationale:
Signs of putrefaction are generally obvious about 24 to 48 hours after death.

Question 6

Question 6:
What is the primary cause of the greenish discoloration of the skin seen during putrefaction?
a) Accumulation of acidic compounds
b) Diffusion of hemolyzed blood into the tissues
c) Rigor mortis
d) Algor mortis

Answer 6

Answer:
b) Diffusion of hemolyzed blood into the tissues

Rationale:
The greenish discoloration of the skin during putrefaction is related to the diffusion of hemolyzed blood into the tissues.

Question 7

Question 7:
Which of the following occurs when putrefaction progresses, involving the release of enzymes and lytic dissolution?
a) Algor mortis
b) Rigor mortis
c) Livor mortis
d) Postmortem autolysis

Answer 7

Answer:
d) Postmortem autolysis

Rationale:
Putrefaction leads to postmortem autolysis, which involves the release of enzymes and lytic dissolution.

Question 8

Question 8:
What is the term used to describe the phenomenon where the skin loosens from underlying tissues during putrefaction?
a) Algor mortis
b) Rigor mortis
c) Slippage
d) Livor mortis

Answer 8

Answer:
c) Slippage

Rationale:
Slippage refers to the loosening of the skin from underlying tissues during putrefaction.

Question 9

Question 9:
At what point does the body become flaccid during the progression of postmortem changes?
a) Within minutes after death
b) About 24 to 48 hours after death
c) Within 6 hours after death
d) At 36 to 62 hours

Answer 9

Answer:
d) At 36 to 62 hours

Rationale:
The body becomes flaccid at 36 to 62 hours after death during the progression of postmortem changes.

Question 10

Question 10:
Which postmortem change is associated with the shrinking of the skin and the development of wrinkles?
a) Rigor mortis
b) Algor mortis
c) Slippage
d) Livor mortis

Answer 10

Answer:
c) Slippage

Rationale:
Slippage is associated with the loosening of the skin from underlying tissues and the development of wrinkles.

Question 11

Question 1:
What is somatic death?

Answer 11

Answer 1:
Somatic death is the death of the entire person.

Question 12

Question 2:
How does postmortem change differ from cellular death in a live body?

Answer 12

Answer 2:
Postmortem change is diffuse and does not involve components of the inflammatory response, unlike cellular death in a live body

Question 13

Question 3:
What are the most notable manifestations of somatic death?

Answer 13

Answer 3:
The most notable manifestations of somatic death are the complete cessation of respiration and circulation.

Question 14

Question 4:
What term is used to describe the reduction of body temperature that occurs after death?

Answer 14

Answer 4:
Postmortem reduction of body temperature is called algor mortis.

Question 15

Question 5:
What causes the purple discoloration of the skin in dependent tissues after death?

Answer 15

Answer 5:
The purple discoloration of the skin in dependent tissues is caused by livor mortis, which occurs due to gravity causing blood to settle in the lowest tissues.

Question 16

Question 6:
What is rigor mortis, and when does it usually develop after death?

Answer 16

Answer 6:
Rigor mortis is the stiffening of muscles after death. It usually develops within 6 hours after death and affects the entire body within 12 to 14 hours.

Question 17

Question 7:
When do signs of putrefaction become generally obvious after death?

Answer 17

Answer 7:
Signs of putrefaction are generally obvious about 24 to 48 hours after death.

Question 18

Question 8:
What causes the greenish discoloration of the skin during putrefaction?

Answer 18

Answer 8:
The greenish discoloration of the skin during putrefaction is thought to be related to the diffusion of hemolyzed blood into the tissues and the production of various denatured hemoglobin derivatives.

Question 19

Question 9:
What happens to the skin during putrefaction?

Answer 19

Answer 9:
During putrefaction, the skin undergoes slippage or loosening from underlying tissues.

Question 20

Question 10:
What microscopic changes are associated with putrefaction?

Answer 20

Answer 10:
At a microscopic level, putrefactive changes are associated with the release of enzymes and lytic dissolution, referred to as postmortem autolysis.
