The term isotonic may refer to: Isotonic (exercise physiology), a type of muscle contraction; Isotonic regression, a type of numerical analysis; Isotonic, one of three types of tonicity that characterize a solution's concentration; see Tonicity#Isotonicity; A sports drink that contains similar concentrations of salt and sugar to the human body
Depiction of a red blood cell in an isotonic solution. A solution is isotonic when its effective osmole concentration is the same as that of another solution. In biology, the solutions on either side of a cell membrane are isotonic if the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.
Isotonic regression is also used in probabilistic classification to calibrate the predicted probabilities of supervised machine learning models. [2] Isotonic regression for the simply ordered case with univariate , has been applied to estimating continuous dose-response relationships in fields such as anesthesiology and toxicology.
A solution can be both hyperosmotic and isotonic. [2] For example, the intracellular fluid and extracellular can be hyperosmotic, but isotonic – if the total concentration of solutes in one compartment is different from that of the other, but one of the ions can cross the membrane (in other words, a penetrating solute), drawing water with it ...
Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical, as the muscle's force changes via the length-tension relationship during a contraction, an isotonic contraction will keep force constant while velocity changes, but an isokinetic ...
Some of the 75,000 U.S. federal workers who the Office of Personnel Management says accepted a resignation buyout offer were ready to retire anyway. Many bristled at Donald Trump's description of ...
Tonicity concept related to the transport of water towards the more concentrated aqueous solution (osmotic transport): In isotonic solutions, water flows equally into and out of the cell (equilibrium). In hypertonic solutions water flows out of the cell and the cell shrinks (plasmolysis).
