Type of calcification where calcium infiltrates into normal tissue, e.g. hypervitaminosis D
Type of calcification where calcium infiltrates into abnormal/damaged tissue, e.g. atherosclerosis or atheroma; damage to tunica intima
Caseous degeneration is seen with what disease?
"Cloudy swelling" is assoc. w/ what pathology?
Albuminous. Membrane injured which effects ionic transfer
"Coagulation"-type of degeneration is assoc. w/ what type of pathology?
"Enzymatic"-type of degeneration is assoc. w/ what organ pathology?
Fatty degeneration in the liver is AKA?
Fatty degeneration in the heart is AKA?
Tabby cat heart
What is the progression of fatty degeneration in the heart?
fatty dot --> Fatty streak --> Atheroma (fatty plaque) --> fibroatheroma (Fibrous tissue, calcium)
"Liquefaction" degeneration is assoc. w/ which system/organ?
CNS (Brain melts, tertiary syphilis, leprosy)
Wallerian degeneration is assoc. w/ what organ?
Peripheral nerves. Degenerates to the next Node of Ranvier.
"Dying back phenomenon"
Zenker's (Waxy) degeneration is assoc. with what?
Hyaline. M/C in skeletal muscle
Muscle replaced w/ hyaline
What does Karyolysis mean?
What does Karyorrhexis mean?
What does pyknosis mean?
Absence of an organ (usually a paired organ)
Small remnants of an organ present (lack of development)
Organ smaller than normal & defective
Decrease in size, typically from disuse. Seen most commonly in muscle
Increase in size
Increase in number of cells (e.g. pregnant uterus, goiter)
Changes from one cell type to another e.g pseudostratified ciliated columnar epithelium changing into stratified squamous in lungs of a smoker
Change in size, shape, or function of a cell. Precancerous, but last stage that can reverse to normal
Complete disorganization of a cell (cancer) e.g. squamous cell carcinoma

Type II collagen is found where?
Disc (specifically nucleus pulposis)
Type III collagen ("reticular collagen") is found where?
Seen in early wound healing
Type IV collagen is found where?
Pneumoconoisis that is caused by silica from sand, rock, or glass. AKA "Rocky Quarry disease"
