Patho terms 1

Pathology Study of changes in structure related to disease/death
Pathophysiology Study of how disease affects body function
Health Ability to maintain homeostasis in normal conditions
Disease Being unable to maintain homeostasis in normal conditions
Etiology Study of the CAUSE of DISEASE
Genetic A disease, condition, or trait inherited as a result of a single gene
Congenital Disease, condition, or trait present at birth
Acquired Disease, condition, or trait developed due to exposure
Idiopathic Disease, condition, or trait without a clearly identified cause
Signs EVIDENCE of a disease that is OBJECTIVE and can be MEASURED
Symptoms EVIDENCE of a disease that is SUBJECTIVE and cannot be measured
Pathogenesis The COURSE of a disease from ONSET to CONCLUSION
Chronic Disease that DEVELOPS GRADUALLY and lasts LONGER than 3 MONTHS
Remission Lessening severity of symptoms of a disease
Exacerbation Increase in severity of symptoms or signs of disease
Local Condition that is confined to one area
Systemic Condition that affects the entire body
Endoscopy Procedure that uses a fiber optic camera to view internal structures of the body
Radiodensity Ability of an object to STOP or SLOW radiation
X-RAYS Visual recording of differences in RADIODENSITY of anatomical structures
Contrast X-RAYS X-Rays that use contrast media to increase radiodensity of select fluids to produce an image of the structure containing them
Ultrasound Visual recording using soundwaves reflecting off objects in the body
Electrocardiogram Recording of electrical activity of the CARDIAC CONDUCTION SYSTEM (ECG)
Electroencephalogram Recording of electrical activity of the brain, most often the cerebral cortex (EEG)
Spirometry Measures breathing- Any procedure used to measure a persons ability to move AIR or capacities of respiratory system. (Pulmonary function tests)
Chemotherapy Use of chemicals to kill cells in the body. ( Two main types to kill cancer cells OR microorganisms)
Pharmacological Use of DRUGS to TREAT disease
Palliative Any treatment that relieves signs & symptoms without curing the disease.
Prognosis Prediction of the likely outcome or consequences of having a disease
Sequela Consequence of a previous disease
Complications Consequence of a disease you currently have
Terminal A disease likely to cause death
Trauma Damage of a harmful amount of energy. (Mechanical, electrical, radiation, thermal)
Deficiency Lacking in something essential
Intoxication Being exposed to a toxic level of something
Hypertrophy To increase in size
Atrophy To decrease in size
Hyperplasia Increased number of cells (through mitosis)
Metaplasia Change in cell or tissue shape
Dysplasia Irregular or abnormal replacement cells
Neoplasia Growth of cells/tissues into new areas, resulting in a tumor. (Benign, or malignant)
Inflammation Protective response of tissue to injury or infection or irritation(increased blood flow, pain, to region and leukocytosis)
Pyrogens Chemicals that cause fever
Leukocytosis Increased white blood cell production
Exudate Excess fluid that accumulates at inflammation site. (High levels of proteins and neutrophils(WBC)
Serous Exudates Thin, clear, watery fluid that accumulates at inflammation site
Purulent Exudate Thick, creamy white or yellow fluid that accumulates at inflammation site (Pus)
Suppurative inflammation Response to injury or infection leading to production of pus
Regeneration Replacing damaged tissue through mitosis, restoring to its original condition
Repair Replacing damaged tissue with scar tissue
Adhesions Binding of two surfaces by scar tissue
Keloid Scarring Over production of scar tissue, often resulting in a mass that is painful or tender (dermis, subcutaneous layer)
Contracture Shortening of scar tissue over time OR shortening of muscle tissue as a result of fibrotic changes
Stenosis Narrowing of any canal or opening
Sclerosis Process of hardening. As a result of scar formation or accumulation of plaques
Necrosis Tissue death
Prodromal stage Early stage in development of a disease or infection characterized by lack of appetite and energy. "Coming down with something"
Anaphylaxis Severe systemic allergic response characterized by vasodilation (cause severe drop in blood pressure) and bronchoconstriction (result-difficulty breathing)
Immunosurveillance Immune systems constant search for an antigen
Immunotolerance Immune systems ability to recognize and not attack tissues within the body
Incubation Development of infection from the time the infectious organism enters the body until first CLINICAL signs/symptoms
Acute stage Time during infection when clinical signs/symptoms begin to develop
Benign A Nonmalignant neoplasm (tumor)
Malignant A cancerous neoplasm (tumor)
Angiogenesis Development of new blood vessels, especially capillaries
Tumor Markers Proteins produced by tumor cells that can be detected in blood screenings
Carcinoma Malignancy originating in epithelial tissues
Sarcoma Malignancy originating in connective tissue
Glioma Malignancy originating in tissue of the CNS
Carcinogenesis Process of developing a Malignant neoplasm (tumor)
Initiators (of cancer) Carcinogens that INCREASE rate of cancer cell production by activating oncogenes
Promoters (of cancer) Carcinogens that DECREASE the body's ability to find/fight cancer cells by damaging tumor suppressing genes
