The Democratic-Republican Party was the American political party in the 1790s of Thomas Jefferson and James Madison formed in opposition to the centralizing policies of the new Federalist party. It came to power in 1800, and dominated national and state affairs until the 1820s, when it faded away.
Spongy bone of the diaphysis is transformed into compact bone the activity of osteoclast (remove bone and widen marrow cavity). Osteoblast lay down concentric lamellae of bone making the Haversain system [structural unit of bone].
A 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.Spongy tissues make up only 20% of mass in a bone but their surface area is ten times than that of compact bone tissues. Compact bone tissues are the shaft or the outer part of the bone. It is dense and strong. â¢ Spongy bone tissues are found on the inside of a bone. They are porous and have a sponge like appearance having holes in them.
