bone cells are called osteocytes. bone contain matrix calle ossein.matrix layers to form lamella. each lamella has space called lacunae.and each lacunae has one bone cell(osteocyte).i hope it helps. or do u want more? :

I didn't even understand that and i already know about bone cells. Sorry, didn't mean to be rude..
Ok, now about those bone cells:
There are 3 types of bone cells:
-osteblasts- young bone cells that secrete oseine
-osteocytes- mature bone cells, are located in some cavities named osteoplasts
-osteoclasts- giant cells, with many nuclei and a very well developed enzymatic system that constantly "eat" from the bone. A colony of osteoclasts forms a channel inside the bone 1 mm in diameter and several mm in lenght, that is then filled up with osteoblasts that secrete oseine and lead to the "finished" product. This happens al your life and there is an equilibrium between the 2 processes: oesteogenesis and ostelysis. As you grow old, osteolysis is predominant, this making it more likely to have fractures.

Have i answered your question?
