hypotonic

In biological and chemical contexts, this term describes a state of imbalance where a solution has a lower concentration of solutes compared to another. This creates a pressure gradient that forces water to migrate into the more concentrated area, often leading to cellular swelling or bursting. In a medical context, the term refers specifically to a lack of tension in the muscles. This condition, often called hypotonia, results in a floppy or limp quality to the limbs, contrasting with the rigidity found in hypertonic states.
