types of cellular reaction to any type of injury
2 types of reversible tissue changes
progressive tissue changes
regressive tissue changes
this reversible tissue change usually implies an increase in size
progressive tissue change
this reversible tissue change usually implies a decrease in size
regressive tissue change
an irreversible change to injury
Regressive changes (4 types)
type of regressive tissue change in which we have the accumulation or buildup of a substance intracellularly within the protoplasm of cells.
Types of degeneration
(a) Cellular (cloudy) swelling -
(b) Fatty degeneration -
(c) Amyloid disease - .
most common type of degeneration. Similar to edema (excess amounts of tissue fluids which bathe and surround the body cells.) This fluid is between cells. Intracellular, cloudy swelling. The swelling would be transient or temporary.
Cellular (cloudy) swelling -
fatty change - fatty metamorphosis – build up or accumulation of fat within the protoplasm of normal cells. Fat in the liver cells affects the liver.
accumulation or buildup of amyloid, a waxy starch-like substance within the normal protoplasm of cells. The amyloid is being deposited within the protoplasm of normal cells
Two most common types of amyloid diseases reported:
TB - Typically, in adults, it begins in the lungs.
Osteomyelitis – inflammation of the spongy bone marrow inside bones.
a type of regressive tissue change, in which we have an accumulation or buildup of a substance between the cells
What is the difference between degeneration and infiltration?
where the substances are being deposited
a type of infiltration; the accumulation of pigmented or colored substance between cells.
pigmentation originated outside the body
a color change along the gum line due to lead
black lung disease
the active ingredient of pepto-bismol will cause color change in the small intestines
abnormal buildup of a pigmented or colored substance naturally produced within the body, e.g. jaundice, freckles, moles.
abnormal accumulation or buildup of calcium salts between cell fibers, as in sclerotic vessels, the way the body heals bone fractures.
abnormal accumulation or excess of uric acid, especially seen in the big toe
types of infiltration (3)
another name for birthmarks
a type of regressive tissue change where there is a localized area of dead tissue in the living body.
causes of necrosis (4)
(1) Insufficient blood supply.
(2) Physical agent - temperature extremes, radiation.
(3) Chemical agents
(4) Loss of nerve supply
types of necrosis (3)
(1) Caseous necrosis
(3) Decubitus ulcer
a type of necrosis - Cheeselike in appearance as seen in T.B.
ischemic necrosis plus putrefaction
