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.
Spongy bone (cancellous 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 has more surface area, but it is weaker and not as  dense as compact bone.    Compact Bone is the tough outer layer of bone while spongy bone is  the poro â¦ us bone where the red and yellow marrow is.    Spongy is softer bone, with holes in it. It is found inside the  bone.
