Believe it or not, your bones are contantly breaking... on a microscopic level. When you go running, or jump off of a second story deck, microfissures - tiny cracks - appear in your bone structure.
The function of the osteoclast is to create new bone tissue to fill in those cracks.

osteoclasts are cells that breakdown and reabsorb bone. They act at sites of injury, but most interestingly they will reabsorb bone that has little or no stress upon it. Astronauts live in zero gravity, and therefore there is no stress on the bone. Energy and matter is being wasted by osteocytes maintaining bone that is not being "used". Osteoclasts are triggered to reabsorb this. Whereever stress is applied, through walking etc, then osteocytes will manufacture new bone, and wherever stress is relieved, osteoclasts will recycle to provide material for the osteocytes. Exercise and resistance training then helps to maintain bone density.

Osteoclasts are a the multinucleated cell whose function is to reabsorb and breakdown bone tissue. The immature form of osteoclasts are called osteoblasts.

Osteoclast: A cell that nibbles at and breaks down bone and is responsible for bone resorption.
An osteoclast (from the Greek words for "bone" and "broken")is a multinucleated cell that degrades and reabsorbs bone. They are involved in the natural turnover of bone tissue along with osteoblasts. Osteoclasts arise from haemopoietic cells of the monocyte/neutrophil lineage, specifically CFU-GM.
Osteoclastic activity is also the basis for straightening of the teeth with dental braces.

Do you mean Osteoclasts?
If you do they are multinucleated cell that breaks down and reabsorbs bone.
