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 ...
In the Mediterranean basin, holm oak, cork oak and olives are typical hardwood trees. In addition, there are several species of pine under the trees in the vegetation zone. The shrub layer contains numerous herbs such as rosemary, thyme and lavender. In relation to the potential natural vegetation, around 2% of the Earth's land surface is ...

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 ...
Fibers collected from the cells of a leaf are known as leaf fibers, for example, banana, [7] pineapple (PALF), [8] etc. Abacá banana leaf fibres drying Abacá banana leaf fibres drying Bast fiber: Bast fibers are collected from the outer cell layers of the plant's stem. These fibers are used for durable yarn, fabric, packaging, and paper.
With the phloem destroyed, nutrients cannot reach the roots, and the tree/plant will die. Trees located in areas with animals such as beavers are vulnerable since beavers chew off the bark at a fairly precise height. This process is known as girdling, or ring-barking, and can be used for agricultural purposes.
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 ...
Fomitopsis betulina (previously Piptoporus betulinus), commonly known as the birch polypore, birch bracket, or razor strop, is a common bracket fungus and, as the name suggests, grows almost exclusively on birch trees. The brackets burst out from the bark of the tree, and these fruit bodies can last for more than a year.
