11 Questions
What are the two processes involved in decomposition and their characteristics?
The two processes involved in decomposition are autolysis and putrefaction. Autolysis is the initial stage of decomposition, where enzymes leak from the cells and bacteria consume the internal organs. Putrefaction is the visible stage of decomposition, which includes the bloating phase, decay phase, post decay phase, and dry stage.
What are the signs of the bloating phase in putrefaction?
The signs of the bloating phase in putrefaction include a greenish discoloration on the lower abdomen near the right hipbone, known as the marbling effect. The superficial blood vessels also appear green through the skin. The stomach starts bloating due to gas formation.
What are the gases responsible for the unpleasant smell of death during putrefaction?
The gases responsible for the unpleasant smell of death during putrefaction are hydrogen sulphide, ammonia, carbon monoxide, and methane.
What is the optimal temperature for accelerated decomposition?
Between 25 and 38 degrees Celsius.
What is the effect of multiple external open injuries on decomposition?
It accelerates decomposition.
According to Casper's dictum, how does the decomposition rate in open air compare to a body submerged in water?
A body decomposes twice as fast in open air.
What are the two phenomena that may arrest the progression of putrefaction?
Mummification and adipocere.
What are the four phases of decomposition and how long does each phase typically last?
The four phases of decomposition are bloating (5-6 days), decay (11 days), post decay (starts around the 12th day), and dry stage (3-4 weeks).
What is post mortem purging and when does it occur?
Post mortem purging is the drainage of fluids from the body and it occurs during the decay phase of decomposition.
What insects and animals contribute to faster skeletonisation of an unburied body?
Insects like beetles and animals like rats, dogs, and cats contribute to faster skeletonisation of an unburied body.
What factors can affect the rate of decomposition?
Factors such as sepsis before death, environmental temperature, humidity, and the presence of insects and other animals can affect the rate of decomposition.
Test your knowledge on decomposition processes and learn about autolysis, the first stage of decomposition after death. Explore how cells leak enzymes and bacteria consume internal tissues during this phase.
