Cell Injury And Death Flashcards
What is necrosis
The process that cell undergoes after death
Putrefaction is
Cell death of soft tissues by BACTERIAL ENZYMES or decay with a foul smell
Auto lysis is
A cell killing itself by leaking its proteolytic enzymes
Unprogrammed self death
Autophagy is
Cells recycling itself for its survival or to continue homeostasis
Apoptosis is
Programmed cell death
Programmed cell survival is also called
Autophagy
Coagulation necrosis is
Necrosis where the cells appears normal over time
Occurs in other parts of the body except cns
Necrosis that occur at the lower exterimities are
Gangrene necrosis
Gangrene necrosis is characterized by
And also called
Dark colouration
Also called Diabetic foot
Liquefactive necrosis is
Necrosis that produces pus
Occurs mainly in the cns
Cheese like necrosis is also called
Caseous necrosis
Difference between ischemia and infarction
Ischemia is reduced or no blood flow to an organ temporarily
Infarction is blood supply that has being cut off permanently from ban organ
Ischemia leads to infarction
Fat necrosis occur to
Adipose tissues
Eg breast after surgery
Death by mistake is called
Necrosis
Necrosis only occurs in living things
Autolysis and heterolysis occurs in non living things
Difference between necrosis and apoptosis
Necrosis is water entering a living cell swelling it and the cell burst and die
It kills multiple cell at the same time
Apoptosis is cell shrinking and becoming acidiophillic
Only kills on cell at a time in a cluster
Autolysis in dead pple happen because of
In Autolysis if the cell is not given water as of living things
It will just burst open and it’s enzymes will kill it
Ischemia is primarily caused by
Aertriolar blockage
Ischemia is decreased oxygen supply to an organ
Which of these cell death always leads to inflammation
Necrosis
Apoptosis does not lead to inflammation like necrosis
Eg mensuration
