Introduction & Spectrum of Human Diseases Flashcards
Radiolucent
Allows the passage of x-rays. Appears black. Destruction of
bone.
Radiopaque
Blocks the passage of x-rays. Appears white. Formation of
bone or other mineralized material.
What considerations do you have with radiolucencies?
-well defined or ill defined
-unilocular or multilocular
What considerations do you have with radiopacities?
-well defined or ill defined
Vesicle
A small circumscribed elevated lesion usually less than 1cm in diameter, usually contains serous fluid
raised
-small water balloon
Bulla
Circumscribed elevated lesion that is around 1cm in diameter, usually contains serous fluid
raised
-big water balloon
Pustule
Various sized circumscribed elevations containing pus
Macule
An area that is usually distinguished by a color different from that of the surrounding tissue: It is flat and does not protrude above the surface of the normal tissue.
*can only see not feel
Papule
A small circumscribed lesion usually less than 1cm in diameter that is elevated or protrudes above the surface of normal surrounding tissue.
*NO fluid
Nodule
A circumscribed lesion usually greater than 1cm in diameter that is elevated or protrudes above or below the surface of normal surrounding tissue.
*NO fluid
Pedunculated
Attached by a stem-like or stalk base
Sessile
Describing the base of a lesion that is flat stem-like
Ulcer
A loss of continuity of the epithelium that penetrates to the underlying connective tissue
Plaque
A patch or differentiated area on a body surface
What are the two different types of plaques?
erythroplakia or leukoplakia
Corrugated surface texture
wrinkled
Fissure surface texture
A cleft or grove, normal otherwise, showing prominent depth
Papillary surface texture
Resembling small nipple-shaped projections or elevations found in clusters
