There are three special types of cells that are found only in the bone. These cell names all start with OSTEO because that is the Greek word for bone. OSTEOCLASTS are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells.
Cancellous or Spongey Bone. Cancellous or spongey bone is found forming the core of most flat and irregular bones. It is also very prevalent in the epiphyses(ends) of long bones. The construction of this osseous tissue type is quite different than that of compact bone. One key difference is the absence of osteons! Spongey bone as the name implies is more open and in cross-section offers a compartmentalized appearance not unlike that of a sponge.
