Examples

• The infant showed signs of hypotonicity, with weak muscle control and poor posture.
• Hypotonicity in newborns can be associated with various genetic and neurological conditions.
• The physical therapist worked to improve the child's hypotonicity through targeted exercises.
• When red blood cells are placed in a hypotonic solution, hypotonicity causes them to swell and burst.
• The hypotonicity of the surrounding fluid allowed water to enter the cell by osmosis.
• Doctors assessed the degree of hypotonicity to determine the appropriate treatment plan.
