Grain (Stippling)

Stippling is a phenomenon in which the surface of something becomes spotted or speckled. This can occur in a variety of fields, including medicine and the arts.

One example of stippling is the retina of the eye in some eye diseases or abnormal red blood cells that are stained this way as a result of exposure to basic dyes. This may be a sign of a number of diseases, such as generic hemolytic anemia and lead intoxication.

In art, stippling is used as a drawing and painting technique in which the surface of an image is created by many small dots or speckles. This technique can be used to create a variety of effects, such as creating texture and dimension, as well as creating subtle transitions between colors.

Grain can be achieved in a variety of ways, including the use of pencils, markers, inks, paints and other materials. It can also be created using computer programs using various effects and filters.

One famous example of the use of grain in art is dot painting, also known as "construction" or "impressionism". This technique was popular in the late 19th century and was used by artists such as Georges Seurat and Paul Signac.

In conclusion, graining is an important technique in both medicine and art. It can be used to create a variety of effects and can be achieved in a variety of ways, depending on the material and tools used to create it.



Graininess or mottling is a term used to describe the visual effects that can occur with certain diseases or conditions in the body. In medicine, granularity can appear in various forms and be associated with various diseases.

One example of stippling is the retina, which is a layer of light-sensitive cells located at the back of the eye. In some retinal diseases, such as age-related macular degeneration or diabetic retinopathy, the retina may become grainy due to abnormal cell development and arrangement. This can lead to vision loss and other serious consequences.

Another example of granularity is abnormal red blood cells that are stained red. These red blood cells can be caused by various factors, such as drug exposure, hereditary diseases, or anemia. Stained red blood cells appear granular due to the presence of small red dots or spots on their surface.

Overall, stippling is an important diagnostic sign that can help doctors determine the cause of the disease and develop the most effective treatment plan. However, if you notice granularity in yourself, you need to consult a doctor for diagnosis and treatment.



Grain is a speckled structure that forms on the surface of a tissue or in a living organism. At the macroscopic level, granularity is visible only against the background of other tissues or cells. In living organisms, granularity is manifested in disease processes, since this effect is the appearance of various patterns on the tissues of organs, such as the gallbladder, liver, trachea, lungs and others, after damage to the organ.
