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 ...
At the snout, the needles strengthen into Sharpey's fibres. The speed at which the kype skeleton develops results in many osteoblasts and proteoglycans appearing along the growth zone. The dentary itself is made of compact bone , but the kype tissue contains chondrocytes and cartilage .
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 or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [ 2 ]
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]
Phloem (/ ˈ f l oʊ. əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant.
The fungus can harbor a large number of species of insects that depend on it for food and as breeding sites. In a large-scale study of over 2600 fruit bodies collected in eastern Canada, 257 species of arthropods, including 172 insects and 59 mites, were found. [16] The fungus is eaten by the caterpillars of the fungus moth Nemaxera betulinella ...
