Lesions
Study of disease organ with the naked eye.
Gross examination

Histologic examination
Classification of disease that is associated with structural changes or lesions. This type of disease is studied through gross examination and/or histologic examination.
Organic Disease
Classification of a disease in which body functions are profoundly disturbed despite no associated morphological abnormalities.
Functional disease
Subjective complaints by the patient.
Symptoms
Objective or physical findings; direct observations by the examiner, such as swelling, redness, or test results.
Signs
A characteristic group of symptoms and signs that accompany a disease or are known to frequently occur together but without a known cause; may arise from different diseases
Syndrome
Cause of a disease
Etiology
Progression or process of development of a disease
Pathogenesis
Agent responsible for causing disease
Etiologic agent
Any microorganism that causes disease
Pathogen
A disease of unknown etiologyor cause
Idiopathic
A disease that results from the adverse effects of treatment (drugs, surgery, etc.)
Iatrogenic
A disease acquired while in a hospital or medical facility
Nosocomial
Unrecognized, hidden (e.g., fecal blood)
Occult
Injury caused by a physical extrinsic agent
Trauma
Range of occurrence and tendency to affect certain groups of people more than others
Incidence
Proportion of people who havea specific disease in a given population per unit of time
Morbidity rate
% of population that diesfrom a given disease in a period of time
Mortality rate
Disease of short duration, usually relatively severe
Acute disease
Disease that is often less severe, but continuous or recurring for long periods
Chronic
The study of the transmission, frequency of occurrence, distribution and control of a disease
Epidemiology
Disease that is readily transmitted fromperson-to-person
Contagious
Disease that can spread to a person in various ways (from another person, insect, animal, environmental source, etc.)
Communicable disease
A condition that a person is born with; can either be inherited or arise during fetal development.
Congenital
