os'teÂ·oÂ·clas'tic adj. osteoclast. A specialized bone cell that absorbs bone, allowing for the deposition of new bone and maintenance of bone strength.

Except in growing bone, the rate of bone deposition and bone absorption equal each other so that bone mass remains constant. A mass of osteoclasts absorbs bone from the outer surfaces inward for about three weeks.
