Terms Flashcards
Epidemiology
Study of cause, patterns and effects of disease and health conditions in a given population
Pathophysiology
How disease processes work to cause dysfunction in the body
Pathogenesis
Mechanism that cause disease
Congential
Something born with, and that is present at birth. (ex: Down Syndrome; birthmark).
Neoplasm
“New growth.” Uncontrolled growth of an abnormal cell line. May be benign or malignant.
Psychosomatic
Condition aggravated by mental condition.
Latrogenic
Illness caused by medical provider or treatment.
Idiopathic
Disease or condition with cause unknown.
Organic
Arising from one’s own body
Prodrome
Early symptom that may be indicative of the start of disease
Subacute
between acute and chronic
Subclinical
Disease that has yet to manifest into any clinical symptoms
Sequela (sequelae)
Condition that is the consequence of a previous disease or injury (ex: kidney disease can be a sequela of diabetes).
Endogenous
Produced or originating within an organism
Exogenous
Originating outside the organism
Steady State
Homeostasis for specific mechanism (does not have to have zero net change like equilibrium). (Ex: Na/K pump, maintains constant internal concentration of K. K is therefore in a steady state).
Diffusion
Molecular movement across membrane from area of higher [ ] to lower [ ] via protein channel. No energy required.
Facilitated diffusion
Molecular binding to transporter protein, results in change in shape that passes molecule in/out of cell via diffusion. No energy required.
Primary active transport
Molecular mov’t “upstream” against [ ] gradient. Energy required
Secondary active transport
[ ] gradients enhanced by primary active transporters moving other molecules (besides primary active transported) against gradient.
Osmosis
Diffusion of H2O molecules across membrane. Follow [ ] gradient
Hyperosmotic
Cell volume decreases due to water leaving cell for extracellular space
Hypoosmotic
Cell volume increases due to water entering cell from extracellular space
Reversible cell injury
Cells are able to adapt to, and accommodate stressors
