Inflammation and Repair Flashcards
Abscess
A collection of purulent exudate that has accumulated in a contained space formed by the surrounding tissue.
Actinic
Relating to or exhibiting chemical changes produced by radiant energy, especially the visible and ultraviolet parts of the spectrum; relating to exposure to the ultraviolet rays of sunlight.
Acute
An injury or the course of inflammation that is of short duration.
Angiogenesis
The formation and differentiation of blood vessels.
Atrophy
The decrease in size and function of a cell, tissue, organ, or whole body.
Biochemical mediators
Chemicals in the body that activate responses.
Central
In the context of oral lesions, central indicates that the lesion is within bone.
Chemotaxis
The movement of white blood cells, as directed by biochemical mediators, to an area of injury.
Chronic
An injury or course of inflammation that is of long duration.
C-reactive protein
A nonspecific protein, produced in the liver, that becomes elevated during episodes of acute inflammation or infection.
Cyst
An abnormal sac or cavity lined by epithelium and surrounded by fibrous connective tissue.
Cytolysis
The dissolution or destruction of a cell.
Demastication
When tooth wear is increased by chewing an abrasive substance.
Edema
An excess level of plasma or exudate in the interstitial space that results in tissue swelling.
Emigration
The passage of white blood cells through the walls of small blood vessels and into injured tissue.
Epithelialization
The process of renewal of a new surface layer of epithelium.
Erythema
The redness of the skin or mucosa.
Exudate
A body fluid with a high protein content that leaves the micorcirculation during an inflammatory response that consists of serum that contains white blood cells, fibrin, and other protein molecules.
Fever
An elevation of body temperature to greater than the usual level of 37C.
Fibroblasts
The cells that form fibers as well as intercellular substance.
Fibroplasia
The formation of fibrous tissue as usually occurs in healing.
Fistula
An abnormal passage that leads from an abscess to the body surface.
