osteoclasts definition
The osteoclasts are a type of bone cells. The bone cells are found within the bone tissues, and they are responsible for the make-up of the skeleton of vertebrates. The four main types of bone cells are the (1) osteoclasts, (2) osteoblasts, (3) osteocytes, and (4) lining cells. The osteoclasts, in particular, are large, multinucleated cells that are involved in the absorption and removal of bone, particularly dissolving the fibers and the matrix of bone.
