Medical term:

mineral

[min´er-al]

any naturally occurring nonorganic homogeneous solid substance. There are 19 or more that form the mineral composition of the body; at least 13 are essential to health. These must be supplied in the diet and generally can be supplied by a varied or mixed diet of animal and vegetable products that meet energy and protein needs. For the recommended dietary allowances of common minerals in the United States and Canada, see Appendices 4 and 5. Calcium, iron, and iodine are the ones most frequently missing in the diet. Zinc, copper, magnesium, and potassium are minerals that are frequently involved in disturbances of metabolism. Other essential minerals include selenium, phosphorus, manganese, fluoride, chromium, and molybdenum. Minerals are either electropositive or electronegative; combinations of electropositive and electronegative elements lead to the formation of salts such as sodium chloride and calcium phosphate.

mineral oil a mixture of liquid hydrocarbons from petroleum, available in both light grade (light liquid petrolatum) and heavier grades (liquid or heavy liquid petrolatum). Light mineral oil is used chiefly as a vehicle for drugs, but it may also be used as a cathartic and skin emollient and cleansing agent. Heavy mineral oil is used as a cathartic, solvent, and oleaginous vehicle. Prolonged use of mineral oil as a cathartic should be avoided because it prevents absorption of the fat-soluble vitamins. Lipid pneumonia caused by aspiration of the oil has been shown to occur in those who habitually take it, especially the elderly.

mineral

(mĭn′ər-əl)

An inorganic element, such as calcium, iron, potassium, sodium, or zinc, that is essential to the nutrition of humans, animals, and plants.

mineral

Those metallic elements that are required for optimal functioning of the body. Dietary requirements for minerals range from molar to trace amounts/day; some (e.g., nickel, tin and vanadium) may be required by some plants or animals, but are not known to have a role in human nutrition.

Dietary minerals
Major—Bone: Calcium, phosphate, magnesium.
Major—Electrolytes: Sodium, potassium, chloride.
Minor—Metalloproteins: Iron, copper, manganese, iodine, cobalt, molybdenum, selenium, chromium, fluoride, zinc.
Trace: Nickel, silicon, vanadium, tin.

Mineral

A substance that does not contain carbon (inorganic) and is widely distributed in nature. Minerals play an important role in human metabolism.

mineralocorticoid

[min″er-al-o-kor´tĭ-koid]

any of a group of hormones elaborated by the cortex of the adrenal gland, so called because of their effects on sodium, chloride, and potassium concentrations in the extracellular fluid. They are the adrenocortical hormones that are essential to the maintenance of adequate fluid volume in the extracellular and intravascular fluid compartments, normal cardiac output, and adequate levels of blood pressure. Without sufficient supply of the mineralocorticoids, fatal shock from diminished cardiac output can occur very quickly.

The principal mineralocorticoid is aldosterone, which accounts for most of the activities of this group of hormones. The primary effects of the mineralocorticoids are increasing the reabsorption of sodium and the secretion of potassium in the renal tubules. Secondary effects are related to the reabsorption of water, serum levels of sodium and potassium, anion reabsorption, and secretion of hydrogen ions. The net result of these activities is maintenance of fluid and electrolyte balance and, therefore, adequate cardiac output.

min·er·al·o·cor·ti·coid

(min'ĕr-al-ō-kōr'ti-koyd),

One of the steroids of the adrenal cortex that influences water and electrolyte (particularly sodium and potassium ions) metabolism and balance.

Synonym(s): mineralocoid

mineralocorticoid

(mĭn′ər-ə-lō-kôr′tĭ-koid′)

Any of a group of steroid hormones, such as aldosterone, that are secreted by the adrenal cortex and regulate the balance of water and electrolytes in the body.

mineralocorticoid

Any of the steroid hormones that regulate water and electrolyte equilibrium, acting specifically on renal tubules.
