In the spine, similar fibres join the intervertebral disc to the adjacent vertebrae. [3] Each fibre is accompanied by an arteriole and one or more nerve fibres. [4] Scottish anatomist William Sharpey described them in 1846, although they were also referred to as the claviculi of Gagliardi after Domenico Gagliardi who described them in 1689. [5]
In 1846 he described the skeletal loadbearing fibres that now bear his name, Sharpey's fibres. He was made a member of its council in 1844, and was appointed one of the secretaries in place of Thomas Bell in November 1853, an office which he held until his retirement. He was also for 15 years, from April 1861, one of the members appointed by ...

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]
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.
The alveolar bone proper is also called bundle bone because Sharpey's fibres, part of the PDL, are inserted there. Sharpey's fibres in alveolar bone proper are inserted at a right angle (just as with the cemental surface); they are fewer in number, but thicker in diameter than those found in cementum. [7]
Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear force's gluons.
Additionally, it is noted that because oxytalan fibers are made up of bundles of microfibrils without elastin, they are unable to elongate in response to mechanical stress. [ 9 ] Despite the fact that oxytalan is a significant elastic fiber, we still don't fully understand its purpose or the particular advantages it offers despite all of the ...
