microfibril

 [mi″kro-fi´bril]
an extremely small fibril.

mi·cro·fi·bril

(mī'krō-fī'bril),
A very small fibril having an average diameter of 13 nm; it may be a bundle of still smaller elements, the microfilaments.

microfibril

An extremely thin fibril, or fibre-like strand, which is identifiable only by electron microscopy, and typically composed of glycoproteins and cellulose (for plants) or fibrillin (for animals).

A very small fibril having an average diameter of 13 nm; it may be a bundle of still smaller microfilaments.

microfibril

a group of some two thousand cellulose chains massed together in the CELL WALL. Microfibrils are embedded in an organic matrix giving the cell wall great strength.
