equilibrium

 [e″kwĭ-lib´re-um]
1. harmonious adjustment of different elements or parts; called also balance.
2. a state of chemical balance in the body, reached when the tissues contain the proper proportions of various salts and water. See also acid-base balance and fluid balance.
dynamic equilibrium the condition of balance between varying, shifting, and opposing forces that is characteristic of living processes.

e·qui·lib·ri·um

(ē'kwi-lib'rē-ŭm),
1. The condition of being evenly balanced; a state of repose between two or more antagonistic forces that exactly counteract each other.
See also: equilibrium constant.
2. In chemistry, a state of apparent repose created by two reactions proceeding in opposite directions at equal speed; in chemical equations, sometimes indicated by two opposing arrows (⇄) instead of the equal sign.
See also: equilibrium constant. Synonym(s): dynamic equilibrium
[L. aequilibrium, a horizontal position, fr. aequus, equal, + libra, a balance]

dynamic equilibrium

the ability of a person to adjust to displacements of the body's center of gravity by changing its base of support.

2. chemistry A state of apparent repose created by two reactions proceeding in opposite directions at equal speed; in chemical equations, sometimes indicated by two opposing arrows (↔) or (⇌).

dynamic equilibrium

the apparently steady but actually fluctuating state which is exhibited by stable ecosystems and communities. fluctuations occur within such systems in relation to seasons, life cycles, nutrient cycles, energy cycles, successional stages etc., all within an apparently stable system. Changes thus occur all the time within such a system, even in a so-called climax community, though these changes are usually small so that such systems are said to be ‘stable’ even though they are in fact in a state of constant change.

equilibrium

a state of balance between opposing forces or influences. In the body, equilibrium may be chemical or physical. A state of chemical equilibrium is reached when the body tissues contain the proper proportions of various salts and water. See also acid-base balance and fluid balance. Physical equilibrium, such as the state of balance required for walking or standing, is achieved by a very complex interplay of opposing sets of muscles. The labyrinth of the inner ear contains the semicircular canals, or organs of balance, and relays to the brain information about the body's position and also the direction of body motions. Genetic equilibrium is achieved when the allelic frequencies do not change from generation to generation.
