Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are mineralized only partially at their periphery. [ 2 ] In the skull , the main function of Sharpey's fibres is to bind the cranial bones in a firm but moveable manner; they are most numerous in areas where the bones are subjected to ...
The PDL also undergoes drastic changes with chronic periodontal disease that involves the deeper structures of the periodontium with periodontitis. The fibers of the PDL become disorganized, and their attachments to either the alveolar bone proper or cementum through Sharpey fibers are lost because of the resorption of these two hard dental tissue.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline 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 ...
The final holdouts of a group of monkeys that escaped from a research facility in South Carolina over two months ago have been safely recaptured, the Yemassee Police Department announced on Friday.
Havers' thesis. Clopton Havers (24 February 1657 – April 1702) was an English physician who did pioneering research on the microstructure of bone. He is believed to have been the first person to observe and almost certainly the first to describe what are now called Haversian canals and Sharpey's fibres.
Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear force's gluons.
