fibro-, fibr-, fiber- +
(Latin: fiber [an elongated, threadlike structure]; a combining form denoting a relationship to fibers)
Fiber roughage consists of four categories: cellulose, hemicelluloses, lignins and pectins; found in unrefined foods; such as, wholemeal cereals and flour, root vegetables, nuts and fruit.
It is known to affect bowel functions, probably because of its capacity to hold water in a gel-like form and it is makes an important contribution to the prevention of constipation, diverticulosis (presence of small bulging sacs pushing outward from the colon wall), irritable bowel syndrome (IBS) or recurrent abdominal pain and diarrhea often alternating with periods of constipation, appendicitis, diabetes mellitus (disease associated with abnormally high levels of the sugar glucose in the blood), and cancer of the colon.
Many western diets do not contain enough fiber roughage to satisfy the needs in human bodies.
2. A slender, elongated, threadlike object or structure.
3. In botany, one of the elongated, thick-walled cells that give strength and support to plant tissue.
4. In anatomy, any of the filaments constituting the extracellular matrix of connective tissue.
5. Any of various elongated cells or threadlike structures, especially a muscle fiber or a nerve.
6. A natural or synthetic filament; such as, of cotton or nylon, capable of being spun into yarn.
7. Something that provides substance or texture.
8. Basic strength or toughness; fortitude; such as, lacking in moral fiber.
9. Coarse, indigestible plant matter, consisting primarily of polysaccharides; such as, cellulose, that when eaten stimulates intestinal peristalsis.
It is used in the building industry for insulation. The fibers are irritating to the skin.
This procedure has transformed the management of, for example, gastrointestinal diseases.
In chest disease, fiberoptic bronchoscopy has now replaced the rigid wide-bore metal tube which was previously used for examination of the tracheo-bronchial tree.
Fiberoptic colonoscopy can visualize the entire length of the colon and it is now possible to biopsy polyps (any mass of tissue that bulges or projects outward or upward from a normal body surface level), or suspected carcinomas, and to perform polypectomy (surgical removal of a polyp).
Use of this principle permits transmission of light, and therefore visual images, around sharp curves and corners.
Devices that use fiberoptic materials are useful in endoscopic examinations.
2. A small fiber or a fine thread.
3. A very small filamentous structure, often the component of a cell or a fiber.
2. An insoluble protein that is essential to the clotting of blood, formed from fibrinogen with the action of thrombin (key blood clot promoter).
The substance is produced in threads; after the threads have formed a close meshwork through the blood, they contract, and produce a dense, felted mass.
Fibrin is found in all inflammatory conditions within serous cavities like the pleura, peritoneum, and pericardium, and forms a thick coat upon the surface of the inflamed joints, and in the lung as a result of pneumonia.
2. A soluble protein present in the blood that is activated by thrombin to form fibrin.
Fibrinogen is a clotting factor and is required to prevent major blood loss.
