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.
Cortical bone is dense and forms the surface of bones. It is solid in appearance, and constitutes as 80% of total bone mass. Compact bone is composed of many cylinder shaped units called osteons, or Haversian Systems (after the anatomist who discovered them.).Spongy Bone: Cancellous bone is a type of osseous tissue with a low density and strength but very high surface area, that fills the inner cavity of long bones.Cancellous bone lies between two layers of compact bone, and this helps contribute to bone strength. As you can guess by it's name, it looks spongy, or porous.ortical bone is dense and forms the surface of bones. It is solid in appearance, and constitutes as 80% of total bone mass.
