What is crenated cell?
In biology, crenation describes the formation of abnormal notched surfaces on cells as a result of water loss through osmosis. Cells are usually in an isotonic solution inside the body, meaning that there is the same concentration of solute and water both inside and outside the cells.
What does crenated red blood cells mean?
Crenated red cells have changed from a disc shape to spheres covered with short, sharply pointed projections. they are usually artefactual but may be seen in conditions such as uraemia, GI bleeding and stomach carcinoma. artefactual crenation may be due to slow drying of the smear or aging of blood in the tube.
What does crenation mean in medical terms?
Medical Definition of crenation : shrinkage of red blood cells resulting in crenated margins.
What is the meaning of crenation in biology?
a rounded projection or tooth, as on the margin of a leaf. Anatomy. (in erythrocytes) the state of being or becoming shrunken with a notched or indented edge. a notch between teeth.
What happens when blood cells become crenated?
When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.
What causes crenation?
Crenation is a phenomenon which occurs when cells of animal origin are exposed to a hypertonic solution, meaning that the solution which bathes the cells has a high concentration of solutes. In crenation, the cells shrink and their shapes become distorted, often with a ruffled or scalloped edge.
What is the opposite of crenation?
Crenation (opposite of Lysis -cell swells/destroyed/hypotonic)
What is crenation and when does it happen?
crenation The shrinkage of cells that occurs when the surrounding solution is hypertonic to the cellular cytoplasm. Water leaves the cells by osmosis, which causes the plasma membrane to wrinkle and the cellular contents to condense. A Dictionary of Biology.
What is Acanthocyte?
Acanthocytes are also called spur cells. They are dense, shrunken, and irregularly shaped red blood cells with spikes on the outside. These cells form from changes in the fats and proteins on red blood cells' outer layers. Most adults have a small number of acanthocytes in their blood.
What are ghost cells in urine?
Ghost Cells. If RBCs become swollen in dilute urine to the point that the cell membrane ruptures, the cell loses its hemoglobin so that only the membrane and free hemoglobin remain. These empty membranes are known as "ghost" cells.
What is the definition of crenation?
Crenation Definition. In botany and zoology, crenation refers to the leaf -like scalloped edges of an object such as a leaf or a shell. In biology, crenation describes the formation of abnormal notched surfaces on cells as a result of water loss through osmosis. Cells are usually in an isotonic solution inside the body, ...
Why do red blood cells have crenation?
Red blood cells are prone to undergoing crenation as either a response to ionic changes in the blood or abnormalities in the cell membrane, disrupting the cell’s ability to maintain an isotonic state. There are two different types of crenated red blood cells: echinocytes and acanthocytes. Instead of the usual rounded biconcave shape, both these cells appear with a rounder form and spiny projections on the cell surface.
Why do acanthocytes have spines?
Acanthocytes possess spines on the cell membrane that manifest in uneven and abnormal distributions, numbers and lengths. The irregular morphology is caused by alterations in the membrane lipids as a result of diseases such as abetalipoproteinemia, which causes abnormal lipid concentrations within the blood as well as the inability to make certain lipoproteins vital for cell membranes. Other diseases such as vitamin E deficiency, liver disease or malabsorption may also have the same effect. This type of crenation is irreversible.
Does crenation occur when water is lost from the cell?
B is correct. Crenation can only occur when water is lost from the cell. A would have no effect on the red blood cell and C would cause the cell to explode from excess water entering the cell.
What is the purpose of crenation?
Crenation is a useful technique for preserving food. Salt curing of meat causes crenation. Pickling of cucumbers is another practical use of crenation.
Why do red blood cells have crenations?
In addition to hypertonicity, red blood cells may have a crenated appearance as the result of certain diseases . Acanthocytes are spiked red blood cells that may form from liver disease, neurological disease, and other illnesses. Echinocytes or burr cells are RBCs that have evenly-spaced thorny projections.
What is the term for a scalloped edge?
Anne Marie Helmenstine, Ph.D. Updated May 06, 2019. Crenation is the term used to describe an object having a scalloped or round-toothed edge. The term comes from the Latin word crenatus which means 'scalloped or notched'.

in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. Crenation is the term used to describe an object having a scalloped or round-toothed edge.
Does crenation occur in animals?
While crenation occurs in animals cells, cells that have a cell wall cannot shrink and change shape when placed in a hypertonic solution. Plant and bacterial cells instead undergo plasmolysis. In plasmolysis, water leaves the cytoplasm, but the cell wall does not collapse. Instead, the protoplasm shrinks, leaving gaps between ...
