Lecture 1 - Introduction Flashcards
(21 cards)
The cause of a disease process
Etiology
The mechanism of disease development
Pathogenesis
(True/False) Lesions can NOT be invisible
False, Lesions may be be invisible due to 1) being DEEP within the body AND 2) having a MOLECULAR basis
Name 3 types of invisible lesions…
- Diabetes Mellitus
- Schizophrenia
- PKU (Phenylketonuria)
Name the 6 categories of diseases…
- Developmental
- Infectious
- Neoplastic
- Metabolic
- Immune-mediated
- Reactive
Give EXAMPLES of each of the 6 categories of diseases…
DEVELOPMENTAL
Genetic/Environmental
Examples:
- Cherubism
- Gardner Syndrome
- Amelogenesis Imperfecta
Give EXAMPLES of each of the 6 categories of diseases…
INFECTIOUS
Bacterial/Fungal/Viral
Example:
-Primary Herpetic Gingivostomatitis 18F
Give EXAMPLES of each of the 6 categories of diseases…
NEOPLASTIC
Benign/Malignant
Examples:
-Granular Cell Tumor
-Squamous Cell Carcinoma
Give EXAMPLES of each of the 6 categories of diseases…
METABOLIC
Endocrine
Examples:
- Acromegaly
- Hypothyroidism
- DM
Give EXAMPLES of each of the 6 categories of diseases…
IMMUNE-MEDIATED
Allergy/Hypersensitivity/Autoimmunity
Examples:
- Recurrent Aphthous Stomatitis
- Mucous Membrane Pemphigoid
Give EXAMPLES of each of the 6 categories of diseases…
REACTIVE
Physical/Chemical/Factitial/Iatrogenic
Examples:
- Pyogenic Granuloma
- Gingival Hyperplasia (DM)
Allows the passage of x-rays and is BLACK
Radiolucent
Blocks passage of x-rays and is WHITE
Radiopaque
Vesicle vs Bulla vs Pustule
Vesicle = Smaller (<1 cm)
Bulla = Larger (>1 cm
- BOTH contain serous fluid
Pustule = various sized, contains pus NOT serous fluid
Lobule
Segment/lobe that is part of the whole (adj. ex: lobular)
Macule: an area that is distinguished by a 1)_______ different from the surrounding. Is 2)_______ compared to the surrounding normal tissue. You (can or cannot?) feel
1) Color
2) Flat
3) Cannot
Papule vs Nodule
Papule: SMALL bump (<1 cm)
Nodule: BIG bump (>1 cm) above OR below the surface of surrounding tissue
- BOTH: no fluid
Pedunculated vs Sessile
Pedunculated = Stem-like or stalk base
Sessile = Flat
A loss in continuity of the epithelium that penetrates the underlying tissue
Ulcer
- Erosion is a shallow ulcer
Plaque definition (2 types)
Patch of differentiated area on a body surface
Erythroplakia = Red
Leukoplakia = White
Name the different types of surface texture and what they look like:
1) Corrugated
2) Fissure
3)Papillary
4) Smooth
5) Rough
6) Folded
1) Wrinkled
2) Cleft or groove (geographic tongue)
3) Finger-like projections
4) Smooth
5) Rough
6) Folded
