Oral pathology test 2 Flashcards
Abscess
Collection of purulent exudate that accumulated in a contained space
Actinic
Exhibiting chemical changes that are produced by radiant energy; relates to the exposure of ultraviolet rays of sunlight
Angiogenesis
Formation and differentiation of Blood vessels
Atrophy
Decreased in size and function of a Cell, tissue, organ, or whole body
Bio chemical mediators
Chemicals in the body that activate respones
Central in context of oral lesions
Lesion with in the bone
Chemotaxis
Movement of White Blood cells, directed by biochemical mediators to an area of injury
C-reactive protein
Nonspecific protein, produced in the liver, becomes elevated during acute inflammation or infection
Cyst
Abnormal sac or cavity lined by epithelium And surrounded by fibrous CT
Cytolysis
Dissolution or destruction of the a cell
Demastication
Tooth wear is increased by chewing abrasive substance
Edema
Excess level of plasma or exudate in the interstitial space resulting in tissue swelling
Emigration
Passage of WBC trough the walls of small blood vessels and into injured tissue
Epithelialization
Process of renewal o a surface layer of epithelium
Exudate
Body fluid with high protein content that leaves the micro circulation during an inflammatory response that consists of serum that contains WBC, fibrin, and other protein molecules
Fever
Body temperature greater than 98.6 F (37C)
Fibroblasts
Cells that form fibers and intercellular substance
Fibroplasia
Formation of fibrous tissue that occurs in healing
Fistula
Abnormal passage that leads from an abscess to the surface of the body
Granulation tissue
Initial Connective tissue formed in healing
Granuloma
Lesion composed of a collection of macrophages usually surrounded by a rim of lymphocytes that are formed during chronic inflammation
Hyperemia
Excess of blood within blood vessels in part of the body
Hyperplasia
Enlargement of a tissue or organ resulting from a increase in the number of cells; result of increased cell division
Hypertrophy
Enlargement of a tissue or organ resulting from increase in size of its individual cells but not in the number of cells
Inflammation
Nonspecific response to injury that involves the micro circulation and its blood cells
Injury
Alteration in the environment that causes tissue damage
Keloid
Excessive scarring that mainly occurs in skin with healing
Leukocytosis
Increase in number of WBC circulating in blood
Leukopenia
decrease in the number of WBC circulating in blood
Local
Disease process that is confined to a limited location in the body that is not general or systemic
Lymphadenopathy
Abnormal enlargement of a lymph node
Macrophage
2nd type of WBC to arrive at a site of injury that was originally a monocyte; participates in phagocytosis during inflammation and continues to be active in the immune response
Margination
Process during inflammation in which WBC tend to move to the periphery of the blood vessel at the site of injury
Microcirculation
Small blood vessels, ( Arterioles, capillaries, and venues of the vascular system)
Myofibroblasts
fiberoblasts that have some of the characteristics of smooth muscle cells ; Ability to contract
Necrosis
Pathological death of one or more cell, part of tissues or organ that results from irreversible damage to cells
Neutrophil
1st WBC to arrive at a site of injury; Primarily in Acute inflammation “polymorphonuclear leukocyte”
Opacification
Process of becoming opaque
Opsonization
Enhancement of phagocytosis by a process in which pathogen is marked with opsonins for destruction by phagocytes
Osteoblast
Cell that forms bone
Pavementing
adherence of WBC to blood vessel walls during inflammation
Peripheral
Lesions within the gingival tissue or alveolar mucosa
Phagocytosis
Ingestion and digestion of particulate material by cells
Purulent exudate
Exudate with pus or forming pus
Pyrogens
Fever-inducing substances produced from white blood cells or pathogenic microorganisms
Radicular
Pertaining to the root of a tooth
Regeneration
Process by which injured tissue is replaced with tissue identical to that present before the injury
Repair
Restoration of damaged or diseased tissue by cellular change and growth
Serous exudate
Watery consistency resembles a serum
Systemic
Pertains to or affecting the body as a whole as well as a disease process pertaining to or affecting the body as a whole
Transudatae
Extravasculuar fluid component of blood that passes through the endothelial cell walls of the microcirculaton
White blood cells
Cells in the blood and surrounding tissues called leukocytes, involved in the inflammatory and immune responses
Traumatic injury
Disease process that results from injury that causes tissue damage
Waldeyers ring
Ring of lymphatic tissue formed by the two palatine tonsil, pharyngeal tonsil, lingual tonsil and intervening lymphoid tissue
