Lesson #1 Flashcards
Homeostasis:
- Is a dynamic steady state - not static
- A state of equilibrium.
- Is typically redundant - because it is require to maintain life.
Example of a disease that is very redundant:
Hypoglycemia.
Injury that has adaptable changes to manage it:
Reversible injury.
Injury that causes cell death:
Irreversible injury.
Etiology:
Causative factors of disease.
Pathogenesis:
Mechanism of disease.
Extrinsic:
Disease caused by environmental/outside factors.
Clinical manifestations:
Functional consequences of a disease.
Latrogenic:
Disease caused by medical errors - extrinsic.
Intrinsic:
Starts within the body - ie: an inherited or metabolic disease.
Idiopathic:
- Is a disease type where the causation is unknown.
- 90% of hypertension cases are idiopathic.
Pathogenesis is -
the relationship between an injury and the reaction to injury.
Examples of the pathogenesis - injury/reaction relationships:
Bacterial infection (syphillis) and pulmonary hypertension.
Signs:
Objective manifestations - ie: fever
Symptoms:
Subjective feelings - ie: nausea
Syndrome:
A collection of signs and symptoms associated with a disease.
Lesion:
Structural change - any injury.
