Definition of the noun tonicity

What does tonicity mean as a name of something?

noun - plural: tonicities

  1. the elastic tension of living muscles, arteries, etc. that facilitate response to stimuli

Alternative definition of the noun tonicity

noun

  1. [medicine] The normal presence of tone or tension in a muscle or organ; tonus
  2. [science] The ability of a solution to exert an osmotic pressure upon a membrane

Explanation

Tonicity is a measure of the effective osmotic pressure gradient of two solutions separated by a semipermeable membrane. In other words, tonicity is the relative concentration of solutions that determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution. Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always be in equal concentrations on both sides of the membrane.
