3rd Quarter Pathology Test 2 Flashcards
types of cellular reactions (manners by which a body would respond to injury)
regressive tissue changesprogressive tissue changes
an increase in size is what type of cellular reaction?
progressive tissue changes
a decrease in size is what type of cellular reaction?
regressive tissue changes
Types of regressive tissue changes
degeneration infiltrationnecrosisatrophy
type of regressive tissue change in which there is an accumulation or buildup of a substance INTRACELLULARLY (within) the protoplasm of cells.
degeneration
degeneration is….
intracellular
we diffrentiate types of degeneration according to the type of _________ that is _______
substanceaccumulated
most common type of degeneration.similar to edema. this fluid is between cells. Intracellular, cloudy swelling, There is a temporary accumulation or buildup of fluid within the protoplasm of cells.
cellular (cloudy) swelling
fatty change-fatty metamorphosis-abnormal accumulation of fat within the protoplasm of normal cells.
fatty degeneration
fat in liver cells affects the _______. This would be called __________
liverliver dysfunction (fatty liver degeneration)
intracellular accumulation or buildup of amyloid within the normal protoplasm of cells.Commonly seen in TB - Typically, in adults, it begins in the lungs. Osteomyelitis - inflammation of the spongey bone marrow inside bones. Infectious disease.
Amyloid disease
a waxy starch like substance
amyloid
These two disease are commonly seen in relation to amyloid disease…
TBOsteomyelitis
type of regressive tissue change in which there is an accumulation or buildup of a substance intercellularly (between the cells)
Infiltration
means within the cells
intracellular
means between the cells
intercellular
inflammation of the spongey bone marrow inside bones. Infectious disease.
Osteomyelitis
accumulation or buildup of a pigmented or colored substance
pigmentation
types of infiltration
pigmentationcalcification gout
accumulation of a pigmented or colored substance which originated outside the body
exogenous pigmentation
tattoos, plumbism, (color change along gum line from high elements of lead) anthracosis (cole miner’s disease-black lung), bismuth poisoning (caused from high dosages over time of bismuth-pepto) are examples of…
exogenous pigmentation
a disease that causes a color change along the gum line…from high elements of lead is called
plumbism
cole miner’s disease also called black lung disease is…
anthracosis
abnormal accumulation of pigmented or colored substance that is naturally present or produced within the body
endogenous pigmentation
jaundice, freckles, moles, albinism, birthmarks
endogenous pigmentation
types of pigmentation
exogenousendogenous
increased localized amounts of melanin. Usually a lighter shade of brown.
freckles
benign pigmented tumors usually a darker shade of brown.
moles
complete absence of melanin production
albinism
these are usually shades of red (port wine color)type of benign tumor of blood vascular tissue.
birthmarks
accumulation or buildup of calcium salts between the cell fibers, as in sclerotic vessels.This is also the natural way the body heals bone fractures.
calcification
calcification is also known as…
calcareous infiltration
excess uric acid, especially seen in big toe
gout
process by which you have a localized area of necrotic or dead tissue present during life
necrosis
causes of necrosis..
- insufficient blood supply2. physical agent-temperature extremes, radiation3. chemical gents4. loss of nerve supply
type of dead tissue which is cheese-like in appearance. Has a unique odor. As seen in TB
caseous necrosis
difference between infarction and necrosis…
need to look up
types of necrosis
caseousgangreneDecubitus ulcer
most famous type of necrosis.
gangrene
types of gangrene
moistdry gas
true gangrene, since saprophytes are present and invade the tissue. There is a foul odor present since saprophytes are present. This is the worst possible type of gangrene
moist
It fits this four word definition…ischemic necrosis (localized area of dead tissue that has been caused by the reduction in arterial blood supply ) plus putrefaction. This is why it is considered true.
moist gangrene
Which gangrene is commonly called TRUE GANGRENE?
moist gangrene
localized area of dead tissue present in a living body
necrosis
reduction in arterial blood supply
ischemic
the decomposition of proteins in an anaerobic environment (absence of oxygen)
putrefaction
4 word definition for true gangrene?
ischemic necrosis plus putrefaction
organisms that obtain their food from dead matter
saprophytes
false gangrene; no saprophytes present; no order; nice line of demarcation.
dry gangrene
since saprophytes have not invaded dry gangrene it spreads_________
slowly
only type that is infectious, caused by clostridium perfringens during life; microorganisms cause tissue gas in death
gas gangrene
a bacteria which can cause spores
perfringens
which type of gangrene is the ONLY type that is infectious
gas gangrene
gas gangrene is caused by which of the following type of microorganisms
bacteria (perfringens)
bedsores caused by pressure points which restrict blood flow.
decubitus ulcer
dead epithelial tissue
ulcer
absence or lack of growthA decrease in size of a body part or organ that previously was of normal size.
atrophy
decrease in size of a body part or organ due to decreased functional demand

forms of physiological atrophy
thymus glandsenile atrophybreasts after lactation
located at the base of the neck. Largest and most active during infancy.
Thymus gland
the progressive shrinkage of all organs as part of the natural aging process.
Senile atrophy
decrease in size due to disease
pathological atrophy
examples of pathological atrophyCHECK ACCURACY OF THIS CARD
anorexia nervosa cancerdisease of a body part (muscle) which will decrease in size.
body’s total response to any injury.
INFLAMMATION
Function of inflammation
protection of the body
If possible, inflammation will…
a. Destroy the causative agent.b. Limit the area affected.c. Begin the process of repair - the process to replace destroyed cells with new ones (scar tissue), but not the same as the destroyed cells.
Causes of inflammation
- Physical irritants2. Chemical irritants3. Infectious agents4. Immunological reaction
extremes of temperature - hot or cold.Radiation which is cumulative.
Physical irritants
an exposure to chemical.
Chemical irritants
any type of microscopic pathogens.
Infectious agents
allergic reaction to a immunological shot (autoimmune disease).
Immunological reaction
