HISTOPATH Flashcards
The mechanism of cells when exposed to several stress and stimuli under normal conditions
ADAPTATION MECHANISM
Which type of cell do not typically divide cell division such as parenchymal cells?
STABLE CELL
A type of cell injury which known as point of no return
IRREVERSIBLE INJURY
a type of cell which is frequently dividing to replace the lost cells of the body
LABILE CELL
Type of cell that only undergo cell division to replace injured cell
STABLE CELL
the defective organ shows no resemblance to the normal mature structure
APLASIA
Complete non-appearance growth of organ
AGENESIA
Failure of the organ to reach normal mature size
HYPOPLASIA
Failure of organ to form an opening
ATRESIA
Imperforate anus is an example of what abnormal cell growth?
ATRESIA
This is due to lack of nutritional supply to sustain normal growth
HUNGER / STARVATION ATROPHY
An inactivity or diminished activity or function
ATROPHY OF DISUSE
Too much workload can cause general wasting of tissue
EXHAUSTION ATROPHY
this may secondarily promote diminution of blood supply
PRESSURE ATROPHY
atrophy that is due to lack of hormones needed to maintain normal size and structure
ENDOCRINE ATROPHY
Decrease of uterus size after child birth is an example of?
PHYSIOLOGIC ATROPHY
Increase in SIZE of cells making up the organ
HYPERTROPHY
Increase in NUMBER of cells making up the organ
HYPERPLASIA
it may develop as response to a deficiency that usually occurs when one of paired organs is removed
COMPENSATORY HYPERTROPHY
Transformation of ADULT cell to ADULT cell type
METAPLASIA
Transformation of ADULT cell to EMBRYONIC or FETAL cell
ANAPLASIA
Hypoxic injury can be irreversible after __ for neurons
3-5 MINUTES
Hypoxic injury can be irreversible after __ for myocardial cells and hepatocytes
1-2 HOURS
Hypoxic injury can be irreversible after __ for skeletal muscles
MANY
Which of the reversible changes is the earliest manifestation to be observed?
CELLULAR SWELLING
1 cause of cell injury
ANOXIA
This change in cell size, shape and orientation
DYSPLASIA
What are the changes to be observed in cytoplasmic in irreversible injury
1) Larger cells “cloudy swelling”
2) Increased eosinophilia
Dissolution of nucleus in irreversible injury
KARYORRHEXIS
Fragmentation or segmentation of nucleus in irreversible injury
KARYOLYSIS
Labile cells under this type of cell death
APOPTOSIS
What are the chief morphologic features of apoptosis?
1) chromatin condensation
2) chromatin fragmentation
3) cell shrinkage
4) cytoplasmic bleb formation
5) phagocytosis of apoptotic cells
Which type of cell death has the characteristics of cell shrinkage and no leakage of cellular components?
APOPTOSIS
which type of cell death causes cell swelling and leakage of cellular components leading to inflammation?
NECROSIS
Cell death that is due to sudden cut-off of blood supply or ischemia
COAGULATIVE NECROSIS
Cell death of which the action of hydrolytic enzymes is blocked
COAGULATIVE NECROSIS
On gross, this type of necrosis appears as somewhat firm, or boiled material
COAGULATIVE NECROSIS
A type of necrosis which has complete digestion of cells
LIQUEFACTIVE NECROSIS
On gross, this type of necrosis appears liquefied and creamy yellow due to increase pus
LIQUEFACTIVE NECROSIS
Microscopically, this type of necrosis appears as amorphous granular debri surrounded by granulomatous inflammation
CASEOUS NECROSIS
Microscopically, the affected cells of coagulative necrosis appear as
GHOSTLY
The destruction of adipose cells is due to release of pancreatic lipase
FAT NECROSIS
