A Bugatti Veyron 16.4 Super Sport, the world's fastest road legal production car with a top speed of 431 km/h (268 mph). Top speed (mph) by year. This is a list of the world's record-breaking top speeds achieved by a street-legal production car (as opposed to concept cars or modified cars).
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.
Another difference between compact and spongy bone tissues is that while blood surrounds spongy bone tissues, it is marrow that surrounds bone in case of compact bone tissues. It is in the compact bone tissues that bone marrow is found, which is a yellow colored fluid.In brief: large portion of a bone is comprised of this compact bone tissue (nearly 80%). It is also called dense bone because of its low porosity. It is in the interior side of the bone that we find spongy or cancellous tissues. This is almost porous network of structures having shapes of rods and plates.
