Inflammation
| Term | Definition |
|---|---|
| abscess | a localized pocket of infection or purulent exudate surrounded by inflammation |
| adhesions | an abnormal union of membranous surfaces due to inflammation or injury |
| angiogenesis | the development of new capillaries |
| anorexia | loss of appetite |
| chemical mediators | a chemical released in the body during an inflammatory response or immune response |
| chemotaxis | the movement of cells toward or away from an area of the body in response to chemical signals (e.g., phagocytic cells move to an area of tissue injury). |
| collagen | the common protein making up connective tissue and bone. |
| contracture | shortening of a muscle or scar tissue causing immobility and deformity of a joint or structure |
| diapedesis | the passage of leukocytes through intact capillary walls to a site of inflammation |
| erythrocyte sedimentation rate | the rate at which RBC settle out of a blood specimen (containing anticoagulant); and elevation in ESR is a general characteristic of inflammation. |
| exudate | a fluid that accumulates and may leak from tissue. |
| fibrinogen | the plasma protein that is formed into solid fibrin strands during the clotting process |
| fibrinous | the insoluble protein end product of blood coagulation |
| fibroblast | an immature fiber-producing cell of connective tissue capable of differentiating into a chondroblast, collagenoblast, or osteoblast. |
| glucocorticoids | the steroid hormones from the adrenal cortex, for example, cortisol (hydrocortisone), that increase blood glucose levels and act to decrease inflammation and allergic reactions. |
| granulation tissue | newly developed fragile tissue, consisting pf fibroblasts and blood vessels, formed during healing. |
| granuloma | a nodular destructive mass associated with some chronic inflammation or infection |
| hematorit | percentage of erythrocytes in a blood sample |
| hematopoiesis | the formation of blood or of blood cells in the living body |
| hyperemia | increased blood flow in an area, resulting in a warm, red area |
| interferone | a group of antiviral glycoproteins produced by viral-infected cells |
| intraarticular | into the joint cavity or joint space |
| isoenzymes | cell enzymes specific to certain organs that differ slightly in structure but have similar functions. |
| leukocytes | any of the colorless blood cells of the immune system including the neutrophils, lymphocytes, monocytes, eosinophils, basophils, and their derivatives |
| macrophage | a phagocytic tissue cell of the immune system that may be fixed or freely motile, is derived from a monocyte, and functions in the destruction of foreign antigens |
| malaise | a general feeling of discomfort or unease or of being unwell |
| neutrophil | a granulocyte that is the chief phagocytic white blood cell of the blood |
| perforation | a hole through the wall of a tube or hollow structure |
| permeability | the ability of certain substances to pass in and out of an organic or semi-organic barrier |
| phagocytosis | he engulfing and usually the destruction of particulate matter by phagocytes that serves as an important bodily defense mechanism against infection by microorganisms |
| purulent | like pus (microbes, white blood cells [WBCs], and cell debris; thick, yellowish material in tissue often resulting from bacterial infection |
| pyrexia | fever |
| pyrogens | a substance that causes fever, a rise in body temperature. |
| regeneration | tissue repair through replacement by identical functioning cells. |
| replacement | fibrous tissue formation that takes place when there is extensive tissue damage, or the cells are incapable of mitosis |
| resolution | the process that occurs when there is minimal tissue damage. |
| scar | overgrowth of fibrous tissue consisting of excessive collagen deposits. |
| serous | watery secretions |
| stenosis | narrowing of a tube, valve, or opening (stricture) |
| ulcer | an open crater-like lesion on the skin or mucous membranes |
| vasodilation | widening of the lumen of blood vessels |
