chapter two Flashcards
abscess
a collection of purulent exudate that has accumulated in a contained space formed by tissue
actinic
relating to or exhibiting chemical changes produced by radiant energy
acute
an injury or course of inflammation that is of short duration
angiogenesis
the formation and differentiation of blood vessels
apoptosis
the programmed cell death as apart of an organism’s growth and development
atrophy
abnormal decrease in the number of cells in an organ or tissue
biochemical mediators
chemicals in the body that activate a response
central
lesion is within the bone
chemotaxis
the movement of white blood cells as directed by biochemical mediators
chronic
an injury or course of inflammation that is of long duration
c reactive protein
a non specific protein produced int eh liver that becomes elevated during episodes of acute inflammation or infection
crenation
indentions or grooves on the side of the tongue caused by irritation from other teeth
cyst
an abnormal sac or cavity that is lined by epithelial tissue 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 excessive amount of plasma, results in tissue swelling
emigration
the passage of white blood cells through the cell wall of small blood vessels into injured tissue
epithelialization
the process of renewal of a new surface of epithlium
exudate
a body fluid with a high protein content that leaves the microcirculation during an inflammatory response
fibroblasts
the cells that form fibers as well as intercellular substance
fibrosis
the formation of excess fibrous connective tissue in an organ or tissue
fistula
an abnormal passage that leads from an abscess to the outside of the body
granulation tissue
the initial connective tissue formed in healing
granuloma
a tumorlike mass of inflammatory tissue consisting of a central collection of marcophages
hyperemia
an excess of blood within blood vessels in a part of a body
hyperplasia
an enlargement of a tissue or organ resulting from an increase in the number of cells
hypertrophy
an enlargement of a tissue or organ resulting from an increase in the size of it’s individual cell not the number of cells
keloid
the excessive scaring that mainly occurs in skin in some cases of healing
leukocytosis
an increase in the number of white blood cells circulating in blood
leukopenia
a decrease in the number of white blood cells
opsonization
the enhancement of phagocytosis
parulis
a collection of granulation tissue and abscessed material on the gingiva
perimolysis
dental erosion caused by gastric acid
pyrons
a fever inducing substance produced from either white blood cells or pathogenic microorganisms
