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.
Bone Growth, Remodeling, and Repair. Introduction: After taking a look at the skeletal system, let's take a closer look at bones. This section is going to discuss the cells involved in bones, bone growth, remodeling, repair, and the breaking down of bones as well. Cells Involved: The picture below is from http://acadameic.kellogg.cc.mi.us. It shows how osteoblasts form and how they may differentiate into an osteocyte.
