Q

what are the 3 types of filaments of the cytoskeleton and what are their FX?

Q

which organelle modifies, sorts, and packages proteins for distribution?
what is it’s structure?
how do proteins leave the golgi complex?

A
  • golgi complex
  • consists of 3 -20 golgi cisternae (membranous sacs)

52
Q

which organelles contain powerful digestive enzymes and hydrolytic enzymes, and act as defense?

Q

which organelle has enzymes that can destroy their own cell - autolysis (due to pathology)?

Q

what is programmed “worn out” mechanism of cell death and deletion? This is frequently compared to “programmed cellular suicide” Is regulated by endogenous system of signals and progressive shortening of telomeres.

what is cellular and tissue death within a living organism?

A

necrosis

75
Q

what is cellular and tissue death within a dead body?

A

autolysis

76
Q

when many cells undergo necrosis at once, then definable patterns of necrosis are produced, depending upon the nature of the injury, the type of tissue, and the length of time, what is this an example of?

A

coagulative necrosis

*this is a typical pattern with ischemia and infarction (loss of blood supply and resultant tissue anoxia)

77
Q

an infarct in the brain, as it organizes and is being resolved, is left with empty or cystic spaces - this is called?

A

brain liquefactive necrosis

78
Q

cellular injury to pancreatic acini leads to release of powerful enzymes which damage fat by production of soaps, and they appear grossly as the soft, chalky white areas… this is called?

A

fat necrosis in pancreas

liquefactive component from superimposed infection in addition to coagulative necrosis from loss of blood supply (on a patient with diabetes mellitus) can result in

A

wet gangrene

82
Q

liver injury with chronic alcoholism leads to? and what is the condition called?

A

leads to fibrosis and regeneration of hepatocytes in nodules - this creates firm nodular appearance of liver called cirrhosis
