Retained Earnings. The accumulated profits of a corporation that are not paid out as dividends. Instead, the money is reinvested in the core business or used to pay off debt. Also called accumulated earnings or earned surplus.
In cell biology, molecular biology and related fields, the word intracellular means inside the cell. It is used in contrast to extracellular (outside the cell). The cell membrane (and, in many organisms, the cell wall) is the barrier between the two, and chemical composition of intra- and extracellular milieu (Milieu intÃ©rieur) can be radically different.
Concentrations of intracellular and extracellular cations are as follows: 1  Intracellular potassium concentration averages 140 mEq/L. 2  Extracellular potassium concentration is 3.5 to 5 mEq/L. 3  Intracellular sodium concentration is 12 mEq/ 4 L. Extracellular sodium concentration averages 140 mEq/ L.
