Flashcards in Vocabulary: Parts 1 - 6 Deck (48):
1

A collection of purulent exudate that has accumulated in a cavity formed by the tissue.

Abscess

2

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.

Actinic

3

A course of disease that ¡s either of short duration or one that is both short and relatively severe.

Acute

4

The formation and differentiation of blood vessels.

Angiogenesis

5

The decrease in size and function of a cell, tissue, organ, or whole body.

Atrophy

6

Describes a lesion that is at the center of an involved area; in the context of oral lesions, it indicates that the lesion is within bone.

Central

7

The movement of white blood cells, as directed by biochemical mediators to an area of injury.

Chemotaxis

8

Course of disease persisting for a long time.

Chronic

9

A nonspecific protein, ‘produced in the liver, that becomes elevated during episodes of acute inflammation or infection.

C-reactive protein

10

An abnormal sac or cavity lined by epithelium and surrounded by fibrous connective tissue.

Cyst

11

The dissolution or destruction of a cell.

Cytolysis

12

Excess plasma or exudate in the interstitial space that results in tissue swelling.

Edema

13

The passage of white blood cells through the walls of small blood vessels and into injured tissue.

Emigration

14

The process of being covered with epithelium.

Epithelialization

15

Redness of the skin or mucosa.

Erythema

16

Fluid with a high protein content that leaves the microcirculation during an inflammatory response. An exudate consists of serum that contains white blood cells, fibrin, and other protein molecules.

Exudate

17

An elevation of body temperature to greater than the normal level of 370 C (98.6° F).

Fever

18

The formation of fibrous tissue, as normally occurs in healing.

Fibroplasia

19

An abnormal passage that leads from an abscess to the body surface.

Fistula

20

The initial connective tissue formed in healing.

Granulation tissue

21

A collection of macrophages usually surrounded by a rim of lymphocytes.

Granuloma

22

An excess of blood within blood vessels in a part of the body.

Hyperemia

23

An enlargement of a tissue or organ resulting from an increase in the number of normal cells; the result of increased cell division.

Hyperplasia

24

An enlargement of a tissue or organ resulting from an increase in the size of its individual cells, but not in the number of cells.

Hypertrophy

25

A nonspecific response to injury that involves the microcirculation and its blood cells.

Inflammation

26

A temporary increase in the number of white blood cells circulating in blood.

Leukocytosis

27

A disease process that is confined to a limited location in the body; not general or systemic.

Local

28

Abnormal enlargement of lymph nodes.

Lymphadenopathy

29

The second type of white blood cell to arrive at site of injury; it participates phagocytosis during inflammation and continues to be active in the immune response.

Macrophage

30

A process during inflammation in which white blood cells tend to move to the periphery of the blood vessel at the site of injury.

Margination

31

Small blood vessels, including arterioles, capillaries, and venules.

Microcirculation

32

A fibroblast that has some of the characteristics of smooth muscle cells, such as the ability to contract.

Myofibroblast

33

The pathologic death of one or more cells, or a portion of tissue, or an organ that results from irreversible damage to cells.

Necrosis

34

The first white blood cell to arrive at a site of injury; the primary cell involved in acute inflammation; also called a polymorphonuclear Ieukocyte.

Neutrophil

35

The process of becoming opaque.

Opacification

36

The enhancement of phagocytosis by a process in which a pathogen is marked, with opsonins, for destruction by phagocytes.

Opsonization

37

The adherence of white blood cells to blood vessel walls during inflammation.

Pavementing

38

Located away from the center; in the context of oral lesions, peripheral indicates that the lesion is within the gingival tissue or alveolar mucosa.

Peripheral

39

The ingestion and digestion of particulate material by cells.

Phagocytosis

40

A secretion containing or forming pus.

Purulent

41

Pertaining to the root of a tooth.

Radicular

42

The process by which injured tissue is replaced with tissue identical to that present before the injury.

Regeneration

43

The restoration of damaged or diseased tissues by cellular change and growth.

Repair

44

A secretion having a watery consistency; relating to serum.

Serous

45

Pertaining to or affecting the body as a whole; a disease process pertaining to or affecting the body as a whole.

Systemic

46

The fluid component of blood that normally passes through the endothelial cell walls of the microcirculation.

Transudate

47

A disease process that results from injury that causes tissue damage.

Traumatic injury

48

The ring of lymphatic tissue formed by the two palatine tonsils, the pharyngeal tonsil, the lingual tonsil, and intervening lymphoid tissue.
