Definition of villus in English:

villus

nounPlural villi ˈvɪləsˈvɪləs

Anatomy

Any of the fingerlike or threadlike projections from the surface of certain membranous structures, typically serving to increase surface area and facilitate the passage of fluid or nutrients.
Example sentencesExamples
- The tissue is sent to the laboratory where the fetal villi are dissected from the maternal decidua and either processed directly or cultured for chromosomal, DNA or biochemical analysis.
- Mutants were observed as non-staining ribbons on the surface of the villus.
- The black stained villus projections are probably due to chronic smoke inhalation.
- Microscopic examination demonstrated hydropic degenerated villi with a circumferential trophoblastic cell proliferation and moderate atypia, consistent with a complete hydatidiform mole.
- And the tiny hair-like projections on the cells - the villi (VIL-li) - shrink and may even disappear.
- Taste is determined on the tongue by tiny projections, called villi, which are able to sense relative proportions of the four tastes: salt, sour, yucky and Frosties.
- The colon can be identified by its size and the absence of mucosal folds and villi; the inner surface is smooth.
- Afterwards the samples were stained with haematoxylin-eosin to evaluate the number of villi, villous height and mucosal thickness and with PAS to identify mucous containing cells.
- At this stage it is more or less spherical and covered with villi (frond-like protrusions); these provide a large surface area for exchange of gases, nutrients, water and waste with the maternal blood.
- Nutrients are absorbed in the small intestine through microscopically elongated villi.

Derivatives

villiform

adjective ˈvɪlɪfɔːm

Anatomy

Although the neoplasm contained numerous capillary-sized vessels, clefted spaces and villiform structures were not apparent.
Example sentencesExamples
- Most cells grew in a sheetlike pattern, although rare clefts and villiform structures were seen.
- In some areas the mucosa lining the cyst had a slightly villiform appearance, whereas elsewhere it was flattened and simplified.
- Longnose gar have long, narrow snouts more than twice as long as the rest of the head and they have abundant, sharp, villiform teeth.
- On opening, the colon revealed numerous wormlike or villiform polyps covering almost the entire segment of the sigmoid colon.

villose

adjective ˈvɪləʊs

Anatomy

Flowers in fascicles, pedicels long, slender and villose, 1-5 flowers per inflorescence, 15-25 mm long, calyx obconic and four-ribbed, 4-lobed, white, campanulate, contracted into a stigmatic apex, stamens 8-16; flowers appear March to May.
Example sentencesExamples
- The villose spineflower occurs from Point Reyes in Marin Co., California, to Bodega Bay in Sonoma Co.
- It is easily recognized by its long, stiff (villose) hairs for which it received its specific epithet.

villosity

noun -ˈlɒsɪti

Anatomy

Origin

Early 18th century: from Latin, literally 'shaggy hair'.
