by Prof. Hilbert Barrows Jr. Published 3 years ago Updated 2 years ago

A hypertonic

Hypertonia

Hypertonia is a term sometimes used synonymously with spasticity and rigidity in the literature surrounding damage to the central nervous system, namely upper motor neuron lesions. Impaired ability of damaged motor neurons to regulate descending pathways gives rise to disordered spinal reflexes, increased excitability of muscle spindles, and decreased synaptic inhibition. These consequences re…

solution is one which has a higher solute concentration than another solution. An example of a hypertonic solution is the interior of a red blood cell compared with the solute concentration of fresh water.

A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

Full Answer

What does it mean to say a solution is hypertonic?

There are three different possibilities for the tonicity of a solution:

  • Hypotonic
  • Hypertonic
  • Isotonic

What effect does a hypotonic solution have on a cell?

If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

Definition of hypertonic 1 : exhibiting excessive tone or tension a hypertonic baby a hypertonic bladder. 2 : having a higher osmotic pressure than a surrounding medium or a fluid under comparison.

Why is hypertonic solution?

A hypertonic solution is one that has a higher solute concentration outside the cell than inside. If a cell is placed in a hypertonic solution, the cell will shrink due to water osmotically moving out. The outside solution has higher soluble concentration than inside the cell.

What is isotonic and hypertonic solution?

Isotonic solutions are most commonly used for regular maintenance of clean, healthy sinuses – a soothing wash to remove excess mucus, dust, and allergens – and for helping address such things as post-nasal drip. A hypertonic solution contains a higher concentration of salt than your body's fluids.

What is hypertonic and hypertonic solutions?

Hypertonic refers to a solution with higher osmotic pressure than another solution. In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.

What is hypotonic solution in chemistry?

Hypotonic solution is any solution that has lower osmotic pressure than other solution. In biological fields, it is generally referred to the solution having less solute and more water than other solution.

What is hypertonic solution Class 12?

(i) Hypertonic solution A solution is called hypertonic if its osmotic pressure is higher than that of the solution from which it is separated by a semipermeable membrane.

What is a hypertonic solution?

In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.

How does water move in hypertonic solutions?

Movement of Water in Hypertonic Solutions. Water moves across a semipermeable membrane. Remember, water moves to equalize the concentration of solute particles. If the solutions on either side of the membrane are isotonic, water moves freely back and forth.

What are some examples of hypertonic cells?

Hypertonic Example. Red blood cells are the classic example used to explain tonicity. When the concentration of salts (ions) is the same inside the blood cell as outside of it, the solution is isotonic with respect to the cells, and they assume their normal shape and size. If there are fewer solutes outside the cell than inside it, ...

Why is salt water hypertonic?

It's also a problem if you drink too much water . If there is a higher concentration of solutes outside of the cell than inside it, such as would happen if you placed red blood cells in a concentrated salt solution, then the salt solution is hypertonic with respect to the inside of the cells . The red blood cells undergo crenation, which means they ...

Is salt water hypertonic or hypotonic?

But, if you view the situation from the inside of the cell, you could consider the plasma to be hypotonic with respect to the saltwater.

Is each side of a partition isotonic?

Each side of the partition is isotonic with respect to the other if you consider there are 4 moles of ions on each side. However, the side with sodium ions is hypertonic with respect to that type of ions (another side is hypotonic for sodium ions). The side with the potassium ions is hypertonic with respect to potassium ...

Why does a cell shrink in a hypertonic solution?

If a cell is placed in a hypertonic solution, the cell will shrink due to water osmotically moving out. The outside solution has higher soluble concentration than inside the cell. Thus water molecules move from inside to outside the cell. A solution whose concentration is less than the cell sap or inside a cell.

What is the process of a solvent passing from a low concentration to a high concentration?

Osmosis is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane. It is a passive process and happens without any expenditure of energy.

What is turgid solution?

A solution whose concentration is less than the cell sap or inside a cell. A plant cell becomes turgid when putting in a hypotonic solution.

What happens when cells are hypertonic?

When solutions surrounding cells are hypertonic, this will cause the organism to become dehydrated, which can lead to problems such as organ failure.

What is the difference between isotonic and hypotonic?

A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it , and a hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.

How do different solutions affect the cells in your body?

How Different Solutions Affect Your Cells. For the cells in your body, the ideal solution is an isotonic solution. This is because water (which is the major solvent in your body) likes to diffuse from an area of low-solute concentration to an area of high-solute concentration. This process is called osmosis.

What is the importance of maintaining the correct balance of water and solutes?

Maintaining the correct balance of water and solutes will ensure that your body stays healthy. Learning Outcomes. After you have finished, you should be able to: Identify the three types of solutions found in your body. Recall how the different types of solutions affect your cells.

Is salt water hypertonic?

Your cells contain a certain amount of salt, but if you placed them in a solution of salt water that has a concentration of salt higher than what is naturally found in your cells, this solution would be hypertonic. Lesson Summary. Let's review.

Is seawater a hypertonic solution?

With its salt content, seawater is considered to be a hypertonic solution. A hypertonic solution will do just the opposite to a cell since the concentration of solutes is greater outside of the cell than inside. For both human and plant cells, the water will rush out of the cell, and it will shrivel up. When this happens to a plant cell, it is ...

How does water move in a hypertonic solution?

Thus, in a hypertonic solution, water leaves the cell and moves to the environment. This causes the cell to shrivel.

What are some examples of hypertonic environments?

Some animals live in extremely hypertonic environments, such as sea turtles. The ocean is made of salt water and is a hypertonic solution compared to cells. Thus, animals that live an entirely marine life must have strategies for keeping their internal state in homeostasis.

What are the two types of solutions?

There are three main types of solutions: Hypotonic solutions contain a lower concentration of solute compared to the cell. This causes water to rush into the cell and creates an effect opposite of hypertonic solutions. Isotonic solutions are those that have the same concentration of solution compared to the cell.

What is the best solution for plant cells?

There are other types of solutions as well, including: Hypotonic: This solution occurs when the environment has less solute than the cell. It causes water to move into the cell and is the optimal solution for plant cells. However, animal cells can burst, or lyse.

What is a solution made of?

A solution is a mixture made of a solute, which is the substance being dissolved, and a solvent, which the substance that does the dissolving. There are many examples of solutions, including lemonade, saline solution for intravenous injections, glucose solutions used to feed cells grown in a laboratory, and more.

Can plant cells die from hypotonic water?

Thus, plant cells without access to a hypotonic solution of water lose their structure, wilt, and can eventually die. In a hypotonic solution, water flows into the cell. In animal cells that lack a cell wall, this can cause the cell to lyse, or burst. If the blood becomes isotonic, the blood cells and others in the body can burst or die.

Is ocean water a hypertonic solution?

Ocean water is an example of a hypertonic solution. Hypertonic solutions are solutions that have a greater concentration of solute compared to the cell. The solvent is the substance that dissolves the solute. When placed in a hypertonic environment, water moves out of the cell through osmosis, causing it to shrink.

What is hypertonic IV fluid?

So when we say that an IV solution is Hypertonic, what we are really saying is that the hypertonic fluid has a higher solute to solvent ratio than blood does. For the purposes of IV fluid, this means that blood becomes our definition of what “ Isotonic ” means.

What membrane do nurses need to consider when injecting hypertonic solution into the blood vessels?

In addition to the RBC membrane, nurses also need to consider the semi-permeable membrane of the blood vessel wall. When you inject hypertonic solution into the blood vessels, you risk pulling water not only the RBCs, but also from the interstitial space!

What happens when you put an egg in a hypertonic solution?

When you immerse the egg in a hypertonic solution, the water that was inside the egg is pulled out in an attempt to equalize the hypertonic solution around it. And the exact same thing can potentially happen to RBCs if we inappropriately administer a hypertonic solution such as 3% Saline.

What is the purpose of adding sugar to hypertonic IV?

The purpose of adding sugar is to provide extra calories to the patient. The dextrose (sugar) is what makes these 3 solutions hypertonic: there is more solute per liter in the IV solution than there is in the blood.

Can you infuse 3% saline in IV?

Even though hypertonic solutions can be useful, they require caution. Generally speaking, you’ll want to infuse IV solution of 3% Saline VERY slowly. Watch the patient closely for any evidence of intravascular overload (aka too much fluid in the blood vessels).

Can sodium be injected into blood vessels?

Since you are purposely injecting a large amount of sodium into the patient’s blood vessels, water may start moving OUT of the interstitial space and INTO the blood vessels, too! This extra fluid being pulled into the blood vessels can lead to increased blood pressure and pulmonary edema (aka fluid in the lungs).

Is dextrose a hypertonic solution?

So you see that while dextrose solutions are technically hypertonic, they quickly leave the patient with only pure water or saline in the blood vessels, depending on which solution was used. At that point, these solutions behave functionally like either hypotonic or isotonic solutions.

What is hypertonic solution?

A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. This leads to water leaving the cell and flowing into the solution around it.

What is hypertonic saline used for?

Hypertonic saline, particularly 7% or 23% hypertonic saline, is used to treat patients with traumatic brain injuries. It draws fluid out of cells to prevent cerebral edema. Typically, hypertonic saline over 3% is administered in a central line rather than in a standard IV drip.

What are the three types of tonicity?

The three types of tonicity are: hypertonic - more solutes than water (water flows from the cell into the solution; the cell shrinks) hypotonic - more water than solutes (water flows into the cell from the solution; the cell swells) isotonic - water levels between the cell and solution are stable (no water movement) ...

Why is hypertonic saline used?

Hypertonic saline is an osmotic agent uses to reduce the effects of secondary brain injury in patients with traumatic brain injury (TBI). It is known as hypertonic saline because its concentration of sodium is higher than the physiologic concentration of plasma (0.9%). This solution is given during the acute phase of the management ...

How does volume expansion affect the brain?

Volume expansion improves blood pressure and cerebral perfusion pressure leading to better brain oxygenation and reduced risk for secondary damage. Decreasing edema in the vascular endothelium of injured tissues lowers vascular resistance, allowing more blood to flow through the vessels.

Does hypertonic saline affect the brain?

Thus, it modulates the hypoperfusion often seen in secondary brain injury. Hypertonic saline also has neurochemical properties whereby after brain trauma, neuronal membranes may become destabilized, and the neurochemical. environment can be disrupted.

Does saline increase osmolarity?

Once hypertonic saline is administered parent erally, it increases the plasma osmolarity. This increase makes plasma to be hypertonic when compared to cerebral tissue therefore creating an osmotic gradient for drawing of water passively from the brain tissue via the process of osmosis.

Can giving HTS cause hypervolemic?

On the other hand, giving HTS may cause some patients to become hypervolemic. Nurses must carefully observe indicators of fluid status, such as intake and output, patient weight, and available hemodynamic values. Chest X rays should be obtained daily to assess for signs of pulmonary edema (Qureshi & Suarez, 2000).

Is HTS infiltrated?

HTS would also be harmful to local tissues if the intravenous site became infiltrated. The presence of HTS in the tissues of the arm and hand can cause cells of these tissues to become extremely edematous as fluid is pulled in. This dangerous edema can cause tissue damage and even lead to necrosis.

Does hypertonic saline help with hyponatremia?

Thus, HTS can limit secondary injury from neurochemical changes. It also counteracts hyponatremia in the brain.

Why is a solution hypertonic?

A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane. If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume.

What does hypertonic mean?

Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself. That will attract water molecules from the cell leading to the shrinking of the cell. Comment on Ivana - Science trainee's post “Hypertonic means that the...”. Button opens signup modal.

What is the difference between tonicity and osmolarity?

Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane’s permeability to those solutes. Three terms—hyerptonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell:

What is tonicity in biology?

Tonicity is a concern for all living things, particularly those that lack rigid cell walls and live in hyper- or hypotonic environments. For example, paramecia—pictured below—and amoebas, which are protists that lack cell walls, may have specialized structures called contractile vacuoles.

What is the net movement of water across a semipermeable membrane from an area of lower solute concentration to

Formally, osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This may sound odd at first, since we usually talk about the diffusion of solutes that are dissolved in water, not about the movement of water itself.

What happens when a cell is placed in a hypotonic environment?

When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Diagram of red blood cells in hypertonic solution (shriveled), isotonic solution (normal), and hypotonic solution (puffed up and bursting). Image credit: Mariana Ruiz Villareal.

What is the ability of an extracellular solution to make water move into or out of a cell by os

Tonicity. In healthcare settings and biology labs, it’s often helpful to think about how solutions will affect water movement into and out of cells. The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity.
