Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow.The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.ompact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
It makes up the hard exterior of skeletal bones. Spongy bone (cancell â¦ ous bone) is in shorter, flatter bones, and at the ends of long bones. It has more blood vessels and usually contains bone marrow, where red blood cells are produced.pongy bone (cancell â¦ ous bone) is in shorter, flatter bones, and at the ends of long bones.
