Definition of microvillus in English:

microvillus

nounPlural microvilli ˌmʌɪkrəʊˈvɪləsˌmaɪkroʊˈvɪləs

Biology

Each of a large number of minute projections from the surface of some cells.
〔生〕（细胞表面）微小突起物；微绒毛
Example sentencesExamples
- In contrast to the model of a rigid microvillus, recent micropipette measurements indicate that neutrophil microvilli might be elastic enough to extend in response to forces that neutrophils might encounter in vivo.
- These cells are sparse but are easily distinguished from other epithelial cells by the presence of a tuft of blunt, squat microvilli on the cell surface.
- The ratio of the surface area of a microvillus to the area of the unit cell can be determined numerically.
- The diagnosis was confirmed by the ultrastructural demonstration of large desmosomes and long microvilli at the cell surface.
- The luminal surface of the epithelial cells contained few irregular cytoplasmic projections, but cilia or microvilli were absent.

Derivatives

microvillar

adjective ˌmʌɪkrəʊˈvɪləˌmaɪkroʊˈvɪlər

Biology

(of a cell surface) having a large number of minute projections.
the microvillar plasma membrane
Example sentencesExamples
- As the core filaments polymerize, other microvillar proteins (villin, fimbrin, etc.) are mobilized from the cytoplasm and inserted.
- The underlying epithelial cells show irregular light nuclei containing discrete nucleoli and a microvillar layer that is presumably secreting the basal layer of cuticle (arrow).
- Equally a mystery are the mechanisms responsible for the construction and destruction of the microvillar membrane with changes in microvillus length.
