Whoever wears a Panerai on their wrist calls attention to themselves thanks to the watches' unique designs. These impressive watches range from 42 mm to 48 mm in diameter and are descendants of models from the 1930s and 1950s. During this time, Panerai supplied the Italian marines with their diving instruments.
An osteoclast (from the Greek words for bone (á½ÏÏÎ­Î¿Î½), and broken (ÎºÎ»Î±ÏÏÏÏ)) is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton.The osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level by secreting acid and a collagenase, a process known as bone resorption.his last hormone, IL-6, is one of the factors in the disease osteoporosis, which is an imbalance between bone resorption and bone formation. Osteoclast activity is also mediated by the interaction of two molecules produced by osteoblasts, namely osteoprotegerin and RANK ligand.
From Wikipedia, the free encyclopedia. Bone resorption is the process by which osteoclasts break down bone and release the minerals, resulting in a transfer of calcium from bone fluid to the blood. The osteoclasts are multi-nucleated cells that contain numerous mitochondria and lysosomes.These are the cells responsible for the resorption of bone. Osteoclasts are generally present on the outer layer of bone, just beneath the periosteum.Attachment of the osteoclast to the osteon begins the process.one is resorbed by osteoclasts, and is deposited by osteoblasts in a process called ossification. Osteocyte activity also plays a key role in this process. Conditions that result in a decrease in bone mass, can either be caused by an increase in resorption, or a decrease in ossification.
