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.
There are two bone tissue categories. Cortical bone makes up one category while cancellous bone, which is spongy interior bone tissue that makes up 20 percent of the human skeletonâs weight, is in the second category. DXA scan can be used to measure bone mineral density. Cortical bone is the denser, heavier type of bone tissue that is usually found along the shaft of longer bones. Periosteum, the equivalent to endosteum on the outside of the bone, plays a vital role in the healing of fractures.
