Pathology Ch 1
Question | Answer |
---|---|
Disease | Any abnormal disturbance of the function/structure of the human body |
Pathogenesis | Occurs after injury, and is the development of disease |
Manifestations | observable changes |
symptom | patients subjective perception of disease |
sign | objective manifestation detected by physician |
syndrome | group of signs and symptoms that characterizes a specific abnormal disturbance |
asymptomatic | does not produce symptoms |
Etiology | study of the cause of disease |
nosocomial | disease acquired in a hospital |
Iatrogenic | adverse responses to medical treatment itself |
idiopathic | no causative factor can be identified |
Acute | disease with quick onset and last a short period |
chronic | disease that manifests slowly and lasts a long time |
sequelae | lasting effects from acute or chronic disease ( neurological damage from stroke) |
Diagnosis | name of a disease a individual is believed to have |
Prognosis | predicted course and outcome of the disease |
morphology | structure of cells or tissue |
Epidemiology | investigation of disease in large groups |
prevalance | number of cases found in a given population |
incidence | number of new cases found in a given period |
mortality rate | average number of deaths caused by a particular disease in a population |
morbidity rate | incidence of sickness sufficient to interfere with an individuals normal daily routine |
genome | entirety of an organisms hereditary information |
physical maps | used to determine physical location of a gene on a chromosome |
genetic maps | used to assign the distance between genetic markers |
single-nucleotide polymorphisms | genetic variations of single DNA bases |
haplotype | closely linked SNPs on a single chromosome |
Atrophy | generalized decrease in cell size |
hypertrophy | generalized increase in cell size |
hyperplasia | increase in the number of cells in a tissue as a result of excessive proliferation |
metaplasia | conversion of one cell type to another cell type that is normal for that tissue |
dysplasia | abnormal changes of mature cells |
congenital | disease present at birth and resulting from genetic or environmental factors |
hereditary | diseases caused by developmental disorders transmitted genetically from parents/ancestors |
inflammatory | disease that results from the body's reaction to a localized injurious agent |
autoantibodies | when antibodies form against and injure the patients own tissue |
autoimmune disorders | diseases associated with autoantibodies (rheumatoid arthritis) |
infection | an inflammatory process caused by a disease-causing organism |
virulence | ease with which an organism can overcome body defenses |
degenerative | diseases caused by deterioration of the body |
metabolism | sum of all physical and chemical processes in the body |
traumatic | diseases that result from mechanical forces such as twisting or crushing of a body part or from the effects of ionizing radiation |
neoplastic | disease results in new, abnormal tissue growth |
benign neoplasm | composed of well-differentiated cells with uncontrolled growth |
malignant neoplasm | loss of control of both cell proliferation and differentiation and changes functional capabilities |
metastatic spread | spreading of cancer cells resulting in secondary tumor distant from primary lesion |
hematogenous spread | spread via blood vessels |
lymphatic spread | spread via the lymphatic system |
invasion | cancerous cells spread into surrounding tissue by virtue of proximity of the areas |
seeding | cancerous cells travel to a distant site or organ system |
carcinoma | type of cancer derived from epithelial tissue |
sarcoma | type of cancer that arises from connective tissue |
leukemia | arises from blood cells |
lymphoma | arises from lymphatic cells |
"T" classification | size of tumur |
"N" classification | lymph node involvement |
"M" classification | distant metastasis (spreading to other parts of the body) |
The prediction of the course and end of a disease and an outlook based on that prediction best defines its: | prognosis |
A compression fracture of the lumbar spine that results from steroid treatments for pain reduction of arthritis would be an example of what disease? | Iatrogenic |
A disease such as Tay-Sachs syndrome that is transmitted genetically is termed | hereditary |
sickness sufficient to interfere with normal daily routine is termed | morbidity |
Which is considered a symptom of a disease process? A- Bloody stool B- Nausea C- Skin Rash D- Swelling | B- Nausea because it is subjective |
A disease that manifests slowly and is present for a long period of time is said to be: | chronic |
which disease classification is usually associated with the normal aging process? | degenerative |
if 4000 cases of a given disease are found in a give population, this is the: | prevalence of the disease |
the relative ease with which an organism can overcome normal bodily defenses refers to: | virulence |
a neoplastic growth is evaluated to determine its degree of histologic differentiation. This is termed: | grading |
generalized increase in cell size refers to: | hypertrophy |
what refers to abnormal changes in mature cells? | dysplasia |
