How do you assess skin turgor?
You can quickly check for dehydration at home. Pinch the skin over the back of the hand, on the abdomen, or over the front of the chest under the collarbone. This will show skin turgor. Mild dehydration will cause the skin to be slightly slow in its return to normal.
Definition. The state of being turgid or swollen, especially due to high fluid content. Supplement. Turgidity is essential in plant cells to make them keep standing upright. Plant cells that lose much water have less turgor pressure, and tend to become flaccid.
- Turgidity means the condition when a cell is placed in hypertonic solution.the inner concentration of cell is less than outer.So it becomes turgid that means water enters the cell and it becomes swollen.Flacidity means the condition when cell is kept in hypotonic solution.the inner concentration of cell is high than

- Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall. The pressure exerted by the osmotic flow of water is called turgidity. It is caused by the osmotic flow of water through a selectively permeable membrane.
- As the pressure from the water increases inside the cell, it becomes more rigid. This is useful because plants do not have a skeleton. Instead the leaves and shoots can be supported by the turgor pressure, the pressure of water inside their cells. If plant cells lose too much water by osmosis, they become less rigid.
- Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.
- Crenation – shrinking an animal cell by osmosis. Turgid – a plant cell fully inflated with water. Plasmolysed – a plant cell that has lost water causing the cell membrane to be pulled away from the inside of the cell wall. Flaccid – a plant cell that is limp through a reduction of pressure inside the cell.
Here are some signs of dehydration to watch out for:
- Less elasticity in the skin.
- Eyes and fontanel (or soft spot on head) appear sunken.
- Decrease or absence of tears.
- Dry mouth.
- Decrease number of wet diapers.
- If your body is severely dehydrated you may experience fever and chills. Fever, in turn, can worsen dehydration, and the higher the fever, the more dehydrated you may become. In infants, so-called dehydration fever may develop if there is inadequate fluid intake, diarrhea, or vomiting.
- One sign of dehydration is a decrease in the number of wet diapers. When a baby gets very dehydrated, his tongue and mouth look dry, and his eyes may appear sunken. You may even notice that, when he cries, there are no tears, O'Connor says. Those are signs of more severe dehydration.
- For infants under 1 year of age: Consult your doctor. For children 1 year and older: Begin with small frequent sips every 15 minutes, increasing serving size as tolerated. Continue for as long as diarrhea is present. To maintain proper hydration, 4–8 servings (32 to 64 fl oz) of Pedialyte may be needed per day.
