A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
Natural fibers are also used in composite materials, much like synthetic or glass fibers. These composites, called biocomposites, are a natural fiber in a matrix of synthetic polymers. [1] One of the first biofiber-reinforced plastics in use was a cellulose fiber in phenolics in 1908. [1]

Sharpey was born in Arbroath on 1 April 1802, the youngest son of the five children Mary Balfour and Henry Sharpy (sic), a shipowner from Folkestone who died before Sharpey was born. [ 2 ] William was educated at the high school in Arbroath and, in November 1817, began studies at the University of Edinburgh , firstly studying humanities and ...
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants.It is an organic material – a natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression.

It is known to act as a soluble, or viscous, dietary fiber that thickens the fecal mass, an example being the consumption of fiber supplements containing psyllium seed husks. [ 5 ] The inner bark of the slippery elm ( Ulmus rubra ) , a North American tree species, has long been used as a demulcent and cough medicine, and is still produced ...
Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems. Cork, sometimes confused with bark in colloquial speech, is the outermost layer of a woody stem, derived from the cork cambium .
