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]

Although the alveolar process is composed of compact bone, it may be called the cribriform plate because it contains numerous openings known as Volkmann's canals, which allow blood vessels to pass between the alveolar bone and the PDL. The alveolar bone proper is also called bundle bone because Sharpey's fibres, part of the PDL, are inserted ...
Typha / ˈ t aɪ f ə / is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae.These plants have a variety of common names, in British English as bulrush [4] or (mainly historically) reedmace, [5] in American English as cattail, [6] or punks, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as raupō, bullrush, [7 ...
R. taedigera is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods". [ 3 ] They grow up to 16 metres (52 ft) tall and are remarkable for their compound pinnate leaves , the longest in the plant kingdom; leaves of R. regalis up to 25 metres (82 ft ...
In North America, virgin (non-recycled) wood fibre is primarily extracted from hardwood (deciduous) trees and softwood (coniferous) trees. The wood fibre can be extracted as a primary product, or collected during the milling of lumber. [1] Wood fibres can also be recycled from used paper materials. [2]
