Term Detail
GO term:microvillus
Synonym: microvilli
GO id:GO:0005902
Definition:Thin cylindrical membrane-covered projections on the surface of an animal cell containing a core bundle of actin filaments. Present in especially large numbers on the absorptive surface of intestinal cells.
CommentsNote that this term refers to a projection from a single cell, and should not be confused with 'microvillus' as used to refer to a multicellular structure such as that found in the placenta.
Number of paths to term: 2
