Examine the defining features of somatic death. Flashcards
Question 1:
What is the primary manifestation that indicates somatic death?
a) Skin discoloration
b) Rigor mortis
c) Cessation of respiration and circulation
d) Swelling of the body
Answer:
c) Cessation of respiration and circulation
Rationale:
Somatic death is primarily characterized by the complete cessation of respiration and circulation.
Question 2:
What term is used to describe the phenomenon of body temperature falling gradually immediately after death?
a) Algor mortis
b) Rigor mortis
c) Livor mortis
d) Putrefaction
Answer:
a) Algor mortis
Rationale:
The gradual reduction of body temperature after death is known as algor mortis.
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:
c) Livor mortis
Rationale:
Livor mortis is responsible for the purple discoloration of dependent tissues due to the settling of blood.
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:
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:
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:
c) About 24 to 48 hours
Rationale:
Signs of putrefaction are generally obvious about 24 to 48 hours after death.
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:
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:
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:
d) Postmortem autolysis
Rationale:
Putrefaction leads to postmortem autolysis, which involves the release of enzymes and lytic dissolution.
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:
c) Slippage
Rationale:
Slippage refers to the loosening of the skin from underlying tissues during putrefaction.
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:
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:
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:
c) Slippage
Rationale:
Slippage is associated with the loosening of the skin from underlying tissues and the development of wrinkles.
Question 1:
What is somatic death?
Answer 1:
Somatic death is the death of the entire person.
Question 2:
How does postmortem change differ from cellular death in a live body?
Answer 2:
Postmortem change is diffuse and does not involve components of the inflammatory response, unlike cellular death in a live body
Question 3:
What are the most notable manifestations of somatic death?
Answer 3:
The most notable manifestations of somatic death are the complete cessation of respiration and circulation.
Question 4:
What term is used to describe the reduction of body temperature that occurs after death?
Answer 4:
Postmortem reduction of body temperature is called algor mortis.
Question 5:
What causes the purple discoloration of the skin in dependent tissues after death?
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 6:
What is rigor mortis, and when does it usually develop after death?
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 7:
When do signs of putrefaction become generally obvious after death?
Answer 7:
Signs of putrefaction are generally obvious about 24 to 48 hours after death.
Question 8:
What causes the greenish discoloration of the skin during putrefaction?
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 9:
What happens to the skin during putrefaction?
Answer 9:
During putrefaction, the skin undergoes slippage or loosening from underlying tissues.
Question 10:
What microscopic changes are associated with putrefaction?
Answer 10:
At a microscopic level, putrefactive changes are associated with the release of enzymes and lytic dissolution, referred to as postmortem autolysis.
