Patho: Ch. 4 Altered Cellular & Tissue Biology Flashcards
Disease
A deviation in “normal” health, no matter how mild or serious
Infectious Disease
Diseases caused by pathogens (microbes that cause disease)
Non-Infectious Diseases
Diseases caused by genetics, environment, age, etc.
Cancer
Idiopathic Disease
Disease where the cause is unknown, there is no known origin
Iatrogenic Disease
A disease caused as a result of treating another disease
Yeast infection, iatrogenic metastasis
Acute Disease
Disease that comes on quickly and goes away quickly
Doesn’t say how serious
ONLY duration
Chronic Disease
Disease that comes on slowly and lasts a long time
Doesn’t say how serious
ONLY duration
Diagnosis
The identification of a disease, what you have or don’t have
Precedes treatment
Prognosis
The prediction of the course of the disease, and treatment
Follows treatment, future
Remission of disease
Disease is gone, temporary or permanent
Exacerbation of disease
Disease gets worse
Complications of Disease
Problems that arise during treatment, have to be dealt w/ on their own
DURING treatment
Sequelae
Problems that have to be dealt w/ after the disease has run its course
Aftermath of disease
Scar
Predisposing (risk) Factors
Things that increase a person’s susceptibility to certain diseases
Genetic, environmental, behaviors, etc.
Clinical Manifestations of disease
- Signs
- Symptoms
- Local
- Systemic
Sign
Something you can measure
Objective
Fever, rash, etc.
Symptom
Something you can’t measure
Subjective
Pain
Local
Isolated to one location of the body
Can still affect other body symptoms
Systemic
Usually involves multiple body systems
Epithelial Tissue
A lot of cells packed very close together, very little space between them
Skin
Connective Tissue
Few cells w/ a lot of space between them
Blood, bone, tendons, ligaments
Cells in the body are considered one of 3 things
- Normal
- Injured
- Adapted
Cellular Adaptation
When a cell has temporarily changed its behavior due to something abnormal
Types of cellular adaptation
- Atrophy
- Hypertrophy
- Hyperplasia
- Metaplasia
- Dysplasia
