Calcitonin

    A hormone secreted by the thyroid gland which controls the levels of calcium and phosphorous in the blood.

RELATED TERMS
--------------------------------------

Hormone
A chemical substance formed in the body that is carried in the bloodstream to affect another part of the body; an example is thyroid hormone, produced by the thyroid gland in the neck, which affects growth, temperature regulation, metabolic rate, and other body functions.

Thyroid
The gland in the throat that synthesizes thyroid hormones that affect metabolism.

Gland
An organ that releases a chemical. Endocrine glands are ductless and secrete hormones directly into the bloodstream. Exocrine glands secrete externally, either through a tube or duct.

Calcium
Chemical element needed for healthy teeth, bones and nerves

Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.

Calcific bursitis
A bursa is a thin fluid-filled sac that reduces friction forces between tissues of the body. Chronic (repeated of long-standing) inflammation of the bursa (bursitis) can lead to calcification of the bursa. This is referred to as "calcific bursitis." The calcium deposition (calcification) can occur as long as the inflammation is present.

Calcification
Formation of calcific (chalky) material in tissue.

Calcification, nonarteriosclerotic cerebral
Is a genetic neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, dysarthria (poorly articulated speech), spasticity (stiffness of the limbs), ocular (eye) problems, and athetosis (involuntary, writhing movements).

Calcified granuloma
A calcified granuloma is a granuloma containing calcium deposits. Since it usually takes some time for calcium to be deposited in a granuloma, it is generally assumed that a calcified granuloma is an old granuloma.

Calcimimetic
A drug in a class of orally active, small molecules that decrease the secretion of parathyroid hormone (PTH) by activating calcium receptors. The secretion of PTH is normally regulated by the calcium-sensing receptor. Calcimimetic agents increase the sensitivity of this receptor to calcium, which inhibits the release of parathyroid hormone and lowers parathyroid hormone levels within a few hours.

Calcinosis
An abnormal deposit of calcium salts in body tissues, as is seen in some forms of disease.

Calciparine
Calciparine is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): heparin calcium.

Calcium chloride 10 per cent in plastic container is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): calcium chloride.

Calcium deficiency
A low level of calcium in the blood (hypocalcemia) which can make the nervous system highly irritable causing tetany (spasms of the hands and feet, muscle cramps, abdominal cramps, and overly active reflexes). Chronic calcium deficiency contributes to poor mineralization of bones, soft bones (osteomalacia) and osteoporosis and, in children, rickets and impaired growth.

Calcium disodium versenate
Calcium disodium versenate is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): edetate calcium disodium.

Calcium excess
Overly high intake of calcium that can result in elevated levels of calcium in the blood (hypercalcemia). This can cause muscle weakness and constipation, affect the conduction of electrical impulses in the heart (heart block), lead to calcium stones in the urinary tract (nephrocalcinosis), impair kidney function, and interfere with the absorption of iron, predisposing to iron deficiency.

Calcium gluceptate
Calcium gluceptate is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): calcium gluceptate.

A drug that reduces spasm of the blood vessels, lowers blood pressure, and controls angina; acts by selectively blocking the uptake of calcium by the cells.

Calculi
Stones or solid lumps such as gallstones.

Calculi, renal
Kidney stones, by another name. A common cause of blood in the urine and pain in the abdomen, flank, or groin. Occurs in 1 in 20 people at some time in their life. Development of the stones is related to decreased urine volume or increased excretion of stone-forming components such as calcium, oxalate, urate, cystine, xanthine, and phosphate. The stones form in the urine collecting area (the pelvis) of the kidney and may range in size from tiny to staghorn stones the size of the renal pelvis itself . The pain is usually of sudden onset, very severe and colicky (intermittent), not improved by changes in position, radiating from the back, down the flank, and into the groin. Nausea and vomiting are common. Predisposing factors may include recent reduction in fluid intake, increased exercise with dehydration, medications that cause hyperuricemia (high uric acid) and a history of gout. Treatment includes relief of pain, hydration and, if there is concurrent urinary infection, antibiotics. The majority of stones pass spontaneously within 48 hours. However, some stones may not. There are several factors which influence the ability to pass a stone. These include the size of the person, prior stone passage, prostate enlargement, pregnancy, and the size of the stone. A 4 mm stone has an 80% chance of passage while a 5 mm stone has a 20% chance. If a stone does not pass, urologic intervention may be needed. The process of stone formation is also called nephrolithiasis or urolithiasis.

Calculus
Hard residue, commonly known as "tarter," that forms on teeth due to inadequate plaque control, often stained yellow or brown.

Calculus, renal
A stone in the kidney (or lower down in the urinary tract). Also called a kidney stone. The stones themselves are called renal caluli.

Cirrhosis
A disease involving the destruction of liver cells and diminished liver function. Cirrhosis can block blood flow to the liver causing high blood pressure and/or jaundice.

Chiropractic medicine
Chiropractic medicine is a form of treatment that uses manipulative therapy to correct subluxation, which many chiropracters hold are the cause of most disease. Although manipulative therapy has been shown to have some efficacy in treating back pain, headache, and other symptoms of spinal-related conditions, the application of chiropractic medicine as a cure or outside of this specific area is controversial and generally rejected by medical doctors in most countries. Practictioners of chiropractic medicine generally hold themselves out as doctors of chiropratic (D.C.). The use of manipulative therapy by D.C.'s to treat back pain, headache, and other spinal and musculo-skeletal symptoms enjoys wide acceptance by government medical authorities in many nations, where it is covered by many health plans such as Medicare in the United States. Although some medical doctors (M.D.'s) and many doctors of osteopathy (D.O.'s) do perform manipulative therapy, more than 90% of the treatment of back pain by manipulative therapy is performed by D.C.'s. The studies have shown a high level of patient satisfaction with manipulative therapy by persons with back problems.

Chorionic gonadotropin
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the trophoblast (part of the placenta). Its role is to prevent the demise of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans. hCG may have additional functions, for instance it is thought that it affects the immune tolerance of the pregnancy.

Cytoskeleton
System of protein filaments in the cytoplasm of a eukaryotic cell that gives the cell a polarized shape and the capacity for directed movement. Its most abundant components are actin filaments, microtubules, and intermediate filaments.

Cell nucleus
An organelle, found in most eukaryotic cells, which contains most of the cell's genetic material. Nuclei have two primary functions: to control chemical reactions within the cytoplasm and to store information needed for cellular division. Plural: nuclei.

Calcitonin

Carbohydrates

Cholesterol
A substance similar to fat that is found in the blood, muscles, liver, brain, and other body tissues.

Computer Tomography Scan
A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.

CAT scan
Computerized tomography diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.

Corticoids
Substances similar to the hormone of the adrenal glands called cortisone; corticoids are differentiated into two groups mineralocorticoids and glucocorticoids applied both locally and systemically, mainly as anti-phlogistics, immunosuppressives, anti-asthmathics or in the treatment of an allergy.
