Term
Disease
Definition
Any condition that is other than normal (abnormal lab value, clinical signs and symptoms)
Term
Homeostasis
Definition
State of equilibrium of the internal environment of the body regulated by complex mechanism
Term
Congenital
Definition
Disease or defect present at birth, developed in uterus. Can apparent immediately or remain latent until later
Term
Hereditary
Definition
Disease transferred from genes of parent(s) to genes of child
Term
Chromosomal
Definition
Improper cell division
Term
Developmental
Definition
Cells in the fetus don’t migrate to the proper location, structures fuse or divide improperly
Term
Teratogens
Definition
Environmental factors that affect the fetus in uterus, causing chromosomal or developmental abnormalities
Term
Trauma
Definition
Physical injury caused by an external force
Term
Trauma types
Definition
Acceleration-Deceleration, cuts and punctures, poisons and radiation, burns
Term
Infection
Definition
Invasion of the body by a foreign organism, in favorable conditions for organism it will multiply and damage cells and tissue
Term
Infection agents
Definition
Bacteria, virus, fungus and parasites
Term
Idiopathic
Definition
Disease with unknown or uncertain cause
Term
Atrophy
Definition
Disuse or wasting of tissue, cell size decrease, shrinking of organ
Term
Hypertrophy
Definition
Increasing of cell size, enlarging of organ
Term
Hyperplasia
Definition
Increasing of cell number, enlarging of organ
Term
Dysplasia
Definition
New abnormal cell growing
Term
Necrosis
Definition
Injured or damaged cell death
Term
Benign
Definition
Localized tumor, will not invade the organ, will not spread to other organs
Term
Benign neoplasm (tumor)
Definition
Slow rate of growth, well encapsulated, is not invading, compressing the tissue, will not reoccur after removal, cold spot
Term
Fibroma
Definition
Tumor composed of connective tissue
Term
Myoma
Definition
Tumor composed of muscle (common in the uterus, called Fibroma because of a connective tissue covering
Term
Lipoma
Definition
Tumor composed of fat (common under the skin)
Term
Papilloma
Definition
Tumor composed of epithelial tissue (grows from the lining of organs, polyp of GB, wart of skin)
Term
Adenoma
Definition
Tumor composed of glandular epithelial tissue (can be found in liver, kidneys, pancreas, breast)
Term
Cystadenoma
Definition
Serous or mucinous fluid secreted by epithelial tissue that becomes cystic (commonly found in ovaries)
Term
Malignant
Definition
Invasive tumor that destroys the host tissue, spreads to other organs resulting in death of the organism
Term
Malignant neoplasm (tumor)
Definition
Fast rate of growth, not well encapsulated, invades to host tissue, spreads to distant organs, can reoccur after removal, hot spot
Term
Metastases
Definition
Spreading of malignant tumor, can be spread via blood, lymph or by direct contact with adjacent tissue.
Term
Original tumor
Definition
Primary cancer
Term
Metastatic tumor
Definition
Secondary cancer
Term
Redness
Definition
Increased blood supply to the area (Color)
Term
Swelling
Definition
Fluids released into the tissue to dilute toxic agents (Tumor)
Term
Heat
Definition
Tissue temperature increase because of increased blood supply, leads to fever (Calor)
Term
Pain
Definition
Pain can be localized or referred to another area in the body (Dolor)
Term
Loss of function
Definition
Ultimate result of inflammation, this can be reversed (Pallor)
Term
Total healing
Definition
No permanent damage
Term
Immune response
Definition
After the body is exposed to infection, body is building resistance to future infections
Term
Scar tissue
Definition
Formation of fibrous or scar tissue, can affect tissue function if its big
Term
Recurrence
Definition
If disease condition repeats its termed CHRONIC
Term
Hematoma
Definition
Healing process may result in hematoma formation; it’s a blood-filled tumor or blood clot. (sonographically appears like a cyst)
Term
Abscess
Definition
Infections usually are leading to abscess formation, localized pus collection. It is caused by pyogenic collection
Term
Gangrene
Definition
Necrosis cases, if considerable amount of tissue is affected its termed Gangrene. Gangrene will spread to adjacent tissue and must be excised (surgically removed) before healing will take place
