Origin: Formed within English, by compounding. Etymons: micro- comb. form, tubule n.

Etymology: < micro- comb. form + tubule n.

Cell Biology.

A microscopic tubular structure; spec. any of the hollow tubules composed of polymeric tubulin that are present in the cytoplasm, cilia, and flagella of cells and that are involved in the maintenance of cell structure and in aspects of cell motility.
