Wouldn't a higher concentration of solutes cause water to flow out of the cytoplasm, rather than out of the (rest of the) cell? This would agree with the statement that the concentration in the cytoplasm becomes high enough to impair its function. - Molinari 05:51 4 Jul 2003 (UTC)
Hypertonic can also refer to a muscle that is over-excited [1] [2]. Perhaps we need a disambiguation page for hypertonic (biology) and hypertonic (physiology), or maybe they are related? Rhetth 15:00, 18 January 2007 (UTC)
Tonicity and osmolarity are not exactly the same thing. "Osmolarity is defined on the basis of an ideal osmometer - one in which the osmotic membrane allows water to pass but completely prevents the solute from passing." "In contrast, tonicity is defined in terms of the response of cells or tissues immersed in a solution. A solution is considered to be isotonic with a given cell or tissue immersed in it shrinks nor swells..." Osmolarity refers to solutions in compartments divided by a semipermeable membrane, while tonicity refers to cells or tissues and their behaviour (shrinking or swelling) in a solution.

The article is horribly confusing, so I added the {{cleanup}} tag. I think it needs to be rewritten because it is an important concept. As an example, the intro section defines "hypertonic" twice, which seems redundant: "In biology, a hypertonic cell environment has a higher concentration of solutes than inside the animal or plant cell." and "A solution which has a higher concentration of solutes than that in a cell is said to be hypertonic." I can try to rewrite it when I have some time... -- Kshieh 21:41, 20 July 2007 (UTC)
