After all, a nail is sharp, and the inside of the nose is sensitive. Putting a foreign object deep into your nasal cavity isn't particularly comfortable, and it can be certainly painful when the performer is learning to do the trick. However, another obstacle -- sneezing -- can be harder to overcome.
Osteoclasts are the bone cell that destroys bone. This allows bone  remodeling, and allows the skeletal system to act as a reservoir  for minerals to maintain blood mineral â¦ levels. Bone cells that are involved in reabsorption and breakdown of the  bone matrix are referred to as osteoclasts.
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.
