| Term | Definition |
|---|---|
| anaerobic | growing, living, or occurring in the absence of molecular oxygen |
| apoptosis | normal programmed cell death in tissues |
| autopsy | an examination of all or part of a body, including organs, after death to determine the cause of illness or death |
| biopsy | the removal of a small piece of tissue for microscopic examination to determine a diagnosis |
| endogenous | originating from within the body |
| exogenous | originating from outside the body |
| gangrene | necrotic tissue infected by bacteria |
| homeostasis | a relatively stable or constant environment in the body, including blood pressure, temperature and pH, maintained by the various control mechanisms |
| hypoxia | a decrease or insufficient level of oxygen in the tissues |
| iatrogenic | caused by a treatment, procedure or error |
| idiopathic | no known cause |
| inflammation | the response to tissue damage, indicated by redness, swelling, warmth and pain |
| ischemia | decreased blood supply in an organ or tissue |
| lysis | destruction of a cell |
| lysosomal | a membrane-bound vesicle in a cell containing digestive or lytic enzymes, including lysosomes |
| microorganisms | very small living organism, not visible to the naked eye, usually single celled |
| microscopic | visible only when magnified by lenses in a microscope |
| morphologic | the physical size, form, structure and shape of cells or organs |
| probability | the likelihood or chance of an occurance |
| pathophysiology | study of functional or physiological changes in the body as a result of the disease process |
| prodromal | time in the early development of the disease when one is aware of vague changes but the signs are not specific |
| manifestations | clinical evidence or effects, the signs and symptoms of a disease |
| signs | objective indicators of a disease |
| symptoms | subjective feelings |
| prognosis | probability of recovery or other outcomes |
| latent stage | silent stage in which no clinical signs are evident |
| mortality | number of deaths resulting from a particular disease |
| morbidity | disease rates within a group |
| chronic | condition that develops gradually but persists for a long time |
| acute | short term illness that develops very quickly with marked signs |
| syndrome | collection of signs and symptoms occurring together in response to a certain condition |
| exacerbation | time in the course of a disease in which the signs increase |
| anaplasia | cells that are undifferentiated with variable nuclear and cellular structures and numerous mitotic features |
| prophylaxis | a measure or drug designed to prevent a disease |
| necrosis | death or destruction of tissue |
| pyroptosis | type of apoptosis that results in lysis of a cell that releases enzymes that damage nearby cells |
| liquification necrosis | cell death where cells liquify due to release of enzymes from damaged cells |
| coagulation necrosis | cells proteins are denatured by necrosis but retain their shape |
| fat necrosis | fatty tissue is broken down into fatty acids by enzymes |
| caseous necrosis | type of coagulation necrosis which a cheesy substance is produced |
| infarction | area of dead cells that result when tissues do not receive oxygen |
| subclinical | pathologic changes occur but the patient exhibits no obvious manifestations |
