REVERSIBLE CELL INURY Flashcards
2 main types of reversible injury
- CELL SWELLING
- FATTY CHANGE
MOST COMMON & MOST IMPORTANT response to cellular injuries of all types. It’s an early manifestation of cell injury.
CELLULAR SWELLING
Gross appearance of cellular swelling:
ORGAN- are swelling w/ round edges
TISSUE- show slight PALOR or BULGES
in cellular swelling affected cell shows what?
- ENLARGE
- PALE CYTOPLASM
- NUCLEUS is in normal position
what is the staining characteristic of cellular swelling?
MILD- shows CLOUDY SWELLING
Vacuoles of variable size appear in cytoplasm called ?
VACUOLAR DEGENERATION
when vacuoles are severe it’s called ?
BALLOONING DEGENERATION
this imply a sick cell, reversible form of injury & adaptive change may result to cell death
DEGENERATION
it occur mostly on HYPOXIC, TOXIC, ,ETABOLIC . this is defines as abnormal accumulation of lipid within the cell.
FATTY CHANGE
- Lipids first enter the?
- as a?
- lipids are metabolized by?
- lipids are exported from the?
- HEPATOCYTES
- FREE FATTY ACIDS
- HEPATOCTES
- HEPATOCYTES
fatty acids can be synthesized from?
ACETATE
some lipids are estrified to form what?
TG - TRIGLYCERIDES
some lipids are synthesized to ?
CHOLESTEROL or PHOSPHOLIPIDS
some lipids are oxidized for energy and produce what?
KETONE BODIES
Triglycerides must be complex with a LIPID ACCEPTOR PROTEIN called?
APOPROTEIN
