isotonic

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.

[ISO- + Greek tonos, tension; see tone + -IC.]

isotonically i'so·ton'i·cal·ly adv.
isotonicity i'so·to·nic'i·ty (-tə-nĭs'ĭ-tē) n.

Describing solutions that have the same osmotic pressure.

---

Solutions with the same osmotic pressure; often refers to a solution with the same osmotic pressure as body fluids. Hypertonic and hypotonic refer to solutions that are more and less concentrated.

(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.

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. contraction — muscle contraction without appreciable change in the force of contraction; the distance between the muscle's origin and insertion becomes lessened.
• i. 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.
• i. saline — see normal saline.
