C1 HistoPath Flashcards
Metaplasia that pertains to the formation of bones in muscles
myositis ossificans
a form of necrosis in which the architecture of dead tissues is preserved for a span of at least some days
Coagulative necrosis
an increase in the number of cells in an organ or
tissue, usually resulting in increased mass of the organ or tissue.
Hyperplasia
usually applied to a limb, generally the lower leg, that has lost its blood supply and has undergone necrosis (typically coagulative necrosis) involving
multiple tissue planes
Gangrenous necrosis
A localized area of coagulative necrosis
infarct.
a special form of necrosis
usually seen in immune reactions involving blood
vessels.
Fibrinoid necrosis
Decreased nutrients, decreased stimulation
Atrophy
reduced size of an organ or tissue resulting from a
decrease in cell size and number.
Atrophy
This pattern of necrosis typically occurs when complexes of antigens and antibodies are deposited in the walls of arteries.
Fibrinoid necrosis
end result of progressive cell injury
Cell death
prolonged moderate hypoxia, such as that produced
by profound anemia, causes intracellular deposits of
fat, which create grossly apparent bands of yellowed
myocardium alternating with bands of darker, redbrown, uninvolved myocardium
tigered effect)
are reversible functional and
structural responses to more severe physiologic stresses and
some pathologic stimuli, during which new but altered steady
states are achieved, allowing the cell to survive and continue
to function
Adaptations
a pathway of cell death that is induced by a tightly regulated suicide program in which cells destined to die activate enzymes that degrade the cells’ own nuclear DNA and nuclear and cytoplasmic proteins.
Apoptosis
results from decreased protein synthesis and increased
protein degradation in cells
Atrophy
caused by excesses
of hormones or growth factors acting on target cells
Hyperplasia
result of increased production of cellular proteins
Hypertrophy
4 Aspects of Disease Process
- Etiology
- Pathogenesis
- Molecular And Microscopic
- Clinical Manifestations
A type of hyperplasia which increases tissue mass after damage or partial resection
Compensatory hyperplasia
result of denaturation of intracellular proteins and enzymatic digestion of the lethally injured cell
Necrosis
Steatosis and fatty change describe abnormal accumulations of triglycerides within parenchymal cells
Lipids
a reversible change in which one differentiated cell
type (epithelial or mesenchymal) is replaced by another cell type.
Metaplasia
refer to the structural alterations in cells or tissues
that are either characteristic of a disease or diagnostic of an
etiologic process.
Molecular and Morphologic Changes.
