isotonic

 [i″so-ton´ik]
1. of equal tension.
2. denoting a solution in which body cells can be bathed without net flow of water across the semipermeable cell membrane; also, denoting a solution having the same tonicity as another solution with which it is compared.

i·so·ton·ic

(ī'sō-ton'ik),
1. Relating to isotonicity or isotonia.
2. Having equal tension; denoting solutions possessing the same osmotic pressure; more specifically, limited to solutions in which cells neither swell nor shrink. Thus, a solution that is isosmotic with intracellular fluid will not be isotonic if it includes solute, such as urea, that freely permeates cell membranes.
3. In physiology, denoting the condition when a contracting muscle shortens against a constant load, as when lifting a weight. Compare: auxotonic, isometric (2).

/iso·ton·ic/ (-ton´ik)
1. denoting a solution in which body cells can be bathed without net flow of water across the semipermeable cell membrane.
2. denoting a solution having the same tonicity as another solution with which it is compared.
3. maintaining uniform tonus.

isotonic

(ī′sə-tŏn′ĭk)
adj.
1. Of equal tension.
2. Isosmotic.
3. Having the same concentration of solutes as the blood: an isotonic saline solution.
4. Physiology Of or involving muscular contraction in which the muscle remains under relatively constant tension while its length changes.

i′so·to·nic′i·ty (-tə-nĭs′ĭ-tē) n.

isotonic

[ī′səton′ik]

isotonic

Of a fluid that exerts the same OSMOTIC PRESSURE as another, especially as that of the body fluids. Body cells, such as red blood cells, can be immersed in an isotonic solution without being caused to change shape. ‘Normal’ saline is isotonic with blood.

isotonic

(of a liquid) having a fluid state with the same WATER POTENTIAL as another liquid. See HYPOTONIC and Fig. 193 .

isotonic

same osmotic pressure as body fluids

isotonic (īˈ·sō·tˑ·nik),

n muscle contraction that involves change in the muscle length.

3. In physiology, denoting the condition when a contracting muscle shortens against a constant load.

isotonic (ī´sōton´ik),

adj equivalence in osmotic pressure. Specifically used in reference to a solution whose osmotic pressure is equal to that of a body fluid, such as blood plasma or tears, to which the solution is compared.
isotonic muscle contraction,

isotonic

1. of equal tension.
2. denoting a solution in which body cells can be bathed without net flow of water across the semipermeable cell membrane; also, denoting a solution having the same tonicity as another solution with which it is compared.

isotonic contraction
muscle contraction without appreciable change in the force of contraction; the distance between the muscle's origin and insertion becomes lessened.
isotonic dehydration
occurs when the fluid lost is isotonic with serum, as in sweating, simple enteritis, nephrosis. There are therefore no errors of electrolyte balance likely to result.
isotonic saline
see normal saline.
