Patho terms1

Terms One

Electroencephalogram a recording of the electrical activity of the brain, most often recording the cerebral cortex
Spirometry any procedure used to measure a person's ability to move air or the capacities of the respiratory system
Chemotherapy the use of chemicals to kill cells within the body
Pharmacological the use of drugs to treat disease
Palliative any form of treatment that relieves signs and symptoms without curing a disease
Prognosis a prediction of the likely outcome or consequences of having a disease
Sequela a consequence of a previous disease
Complications a morbid process or event occurring during a disease that is not an essential part of the disease, although it may result from it
Terminal a disease likely to cause death
Trauma the transfer of a harmful amount of energy. Energy maybe mechanical, electrical, radiation or 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 an increase in the rate of mitosis and therefore cell number
Metaplasia a change in cell or tissue structure
Dysplasia irregular cell or tissue structure, often considered a potentially cancerous change
Neoplasia growth of cells and tissue into new areas, resulting in a tumor. Benign or malignant
Inflammation a protective response of tissue to injury or infection causes an increase in blood flow and pain in affected region, as well as leukocytosis
Pyrogens chemicals that cause a fever
Leukocytosis an increase in the number of WBC to more than 10,000 per mm3. WBC 15,000-25,000 occurs as result of infection, inflammation or hemorrhage
Exudate the excess fluid that accumulates at the site of inflammation. contains a high level of proteins and neutrophils when compared to normal tissue fluid.
Serous exudate a thin, clear, water fluid that accumulates at the site of inflammation
Purulent exudate a thick, creamy white or yellow fluid that accumulates at the site of inflammation. Pus
Suppurative inflammation a response to injury or infection that leads to the production of pus
Regeneration replacing damaged tissue through the process of mitosis, restoring the tissue to its original condition
Repair replacing damaged tissue with scar tissue
Adhesions the binding together of two surfaces by scar tissue
Keloid scarring the over production of scar tissue that sometimes occurs in the dermis and subcutaneous layer and results in a mass of scar tissue that is often tender or painful
Contracture the shortening of scar tissue over time or the shortening of muscle tissue as a result of fibrotic changes
Stenosis the narrowing of any canal or opening, such as the intestine, a blood vessel or a heart valve
Sclerosis process of hardening results from scar formation or accumulation of plaque
Necrosis tissue death
Prodromal stage an early stage in development of a disease or infection that is characterized by a lack of appetite and lack of energy
Anaphylaxis a severe, systemic allergic response that is characterized by vasodilation and bronchoconstriction
Immunosurveillance the immune system's constant search for an antigen
Immunotolerance the immune system's ability to recognize and not attack normally occurring tissues within the body
Incubation the development of an infection from the time the infectious organism enters the body until the appearance of the first clinical signs and symptoms
Acute stage the time during an infection when clinical signs and symptoms begin to develop
Benign a nonmalignant neoplasm
Malignant a cancerous neoplasm
Pathology the study of changes in cell/tissue structure related to disease or death
Pathophysiology the study of how disease affects body function
Health having the ability to maintain homeostasis when exposed to normal conditions
Disease being unable to maintain homeostasis when exposed to normal conditions
Etiology the study of the cause of a disease
Genetic a disease, condition, or trait that is inherited as a result of a single gene
Congenital a disease, condition, or trait that is present at birth
Acquired a disease, condition, or trait that developed because of being exposed to something during your life
Idiopathic without a clearly identified cause
Signs evidence of disease that is objective and can be seen, measured or recorded
Symptoms evidence of disease that is subjective and cannot be seen, measured or recorded
Pathogenesis the events that lead to the development of a disease and the signs and symptoms that occur as the disease progresses
Acute a disease that develops and resolve rapidly
Chronic a disease that develops gradually and last three months or longer
Remission the lessening in severity of the symptoms of a disease
Exacerbation an increase in the severity of a disease or any of its signs or symptoms
Local a condition that is confined to one area
Systemic a condition that affects the entire body
Endoscopy a procedure that utilizes a fiber optic camera to view structures inside of the body
Radiodensity the ability of an object to stop or slow radiation
X-rays a visual recording of differences in radiodensity of anatomical structures
Contrast x-rays x-rays that utilize a contrast media to increase radiodensity of selected fluids within the body producing an image of the structures containing the fluid
Ultrasound a visual recording of differences in the rate of return and intensity of sound waves reflected off of objects within the body
Electrocardiograms a recording of the electrical activity of the cardiac conduction system
Angiogenesis the development of new blood vessels especially capillaries
Tumor Markers proteins produced by tumor cells that can be detected in screening tests of the person's blood
Carcinoma a malignancy that originates in epithelial tissue
Sarcoma a malignancy that originates in connective tissue
Glioma a malignancy that originates within the tissue of the CNS
Carcinogenesis the process of developing a malignant neoplasm
Initiators (of cancer) carcinogens that increase the rate of cancer cell production by activation oncogenes
Promoters (of cancer) carcinogens that decrease the body's ability to find and fight cancer cells by damaging tumor suppressing genes
