Hypertonic Solution - Definition, Meaning, Examples & Diagram
As hypertonic solution contains more solutes and less water than the cell sap, the cell will lose water and eventually shrink. Following the rule of osmosis, water will start to move from its region of higher concentration to lower across the cell membrane, i.e., from the cell to the external medium (exosmosis).Thus a cell maintains the equilibrium of water content both internally and externally.

Hypertonic / Tight Muscles of the Low Back and Pelvis
By tightening, the musculature acts as a splint to the area, blocking motion and thereby allowing the tissues of the area to rest and heal. Therefore, overt traumatic injury or irritation to any tissues of the joints of the low back and pelvis can cause the muscles of the region to tighten and splint the area. 3.

Hypertonic Solution | Definition, Significance & Examples
Nov 21, 2023A hypertonic solution is a solution that has a greater concentration of solute compared to the cell and less water. To understand this definition, we also need to understand solutions. A solution ...

Hypertonic Solution - Definition and Examples | Biology Dictionary
Hypertonic Solution Overview. as the water moves between the two solutions. This movement of ions and water is extremely important to cells. Cells use ion gradients for a number of purposes. For example, plant cells use a hypertonic solution within their central vacuole to help draw water into the vacuole. This expands the chamber and allows ...

Hypertonic Pelvic Floor: Symptoms, Causes & Treatment - Cleveland Clinic
The causes of this condition can be complex. Factors that may increase your risk for hypertonic pelvic floor include: Habitually holding in your urine or stool. Some people do this as children and continue the practice into adulthood. ... Medications to manage symptoms such as pain, anxiety, constipation or frequent urination.

Isotonic vs. Hypotonic vs. Hypertonic Solution | Biology
Isotonic vs. Hypotonic vs. Hypertonic Solution. The effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells is the same. However, due to the cell walls of plants, the visible effects differ. Although some effects can be seen, the rigid cell wall can hide the magnitude of what is going on inside.

Can I kill bacteria with distilled water? Given that bacteria are hypertonic (contain more salts) compared to distilled water, and that they rely on ion concentration differences across the plasma membrane to survive,...
Indeed, bacteria are susceptible to osmotic stress from being in pure water. They are also susceptible to starvation in such an environment. However, _wild_ bacteria tend to have many mechanisms that protect against this and allow them to survive in spite of being exposed to water. Note, also, that ...

Spasm
A hypertonic muscle spasm is a condition of chronic, excessive muscle tone (i.e., tension in a resting muscle). In this case, the hypertonic muscle tone is excessive, and the muscles are unable to relax. A subtype of spasm is colic. wikipedia.org

Forced breathing, a.k.a _hyperventilation_ , causes hypertonic dehydration. Possible causes of hypertonic dehydration include excessive loss of hypotonic fluid (e.g., sweat) or hyperventilation.

What happens to the red blood cell in CaCl₂ solution? Here's the problem: One red blood cell is placed in a hypertonic solution of NaCl, another is placed in a solution of CaCl2 equimolar with the NaCl solution. What...
The reason why the cell would shrink more in CaCl2 solution is because it has a higher van't Hoff factor i.e. total number of dissociated ionic species per solute molecule (it is 2 for NaCl whereas it is 3 for CaCl2). ( _Nonionic solutes do not dissociate and will therefore have a van't Hoff factor ...

Crenation
In a hypertonic environment, the cell has a lower concentration of solutes than the surrounding extracellular fluid, and water diffuses out of the cell Plasmolysis is the term which describes plant cells when the cytoplasm shrinks from the cell wall in a hypertonic environment. wikipedia.org

Hypertonic - Academic Kids
Hypertonic. In biology, a hypertonic cell environment has a higher concentration of solutes than in cytoplasm. In a hypertonic environment, osmosis causes water to flow out of the cell. If enough water is removed in this way, the cytoplasm can become so concentrated that the cell has difficulty functioning. In plant cells, the effect is more ...
