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.
There are three types of cell present in bone that are of particular interest â osteoblasts, osteocytes and osteoclasts, which are respectively responsible for the production, maintenance and resorption of bone. 1  Osteoblasts. 2  Mononucleated âbone-formingâ cells found near the surface of bones. Mononucleated âbone-formingâ cells found near the surface of bones. 2  They are responsible for making osteoid, which consists mainly of collagen. 3  The osteoblasts then secrete alkaline phosphatase to create sites for calcium and phosphate deposition, which allows crystals of bone mineral to grow at these sites.
