As with the other markings, their size and shape reflect the size of the vessels and nerves that penetrate the bone at these points. See answer (1) Best Answer. What are the three smallest bones in the human body? They are usually parallel to the bone's surface. Compact bone tissue consists of osteons that are aligned parallel to the long axis of the bone, and the Haversian canal that contains the bone's blood vessels and nerve fibers. These osteogenic cells are undifferentiated with high mitotic activity and they are the only bone cells that divide.

The compact bone also provide strong mechanical levers, against which the muscles can create movement. Because the matrix is mineralized (rather than aqueous), nutrients and waste cannot diffuse through the matrix. b) osteoclasts. Due to the strong nature of compact bone, compared to spongy bone, it is the preferred tissue for strength. We use cookies to give you the best possible experience on our website. Like osteoblasts, osteocytes lack mitotic activity. Bone contains three types of cells: osteoblasts, which deposit bone; osteocytes, which maintain the bone; and osteoclasts, which resorb bone.
