ANATOMY

Detailed explanation-1: -Spongy bone has lots of needle like pieces called trabeculae and lots of spaces. We classify bones by their shape. Long-longer than wide, compact bone outside, some have spongy bone on the interior. Short-cuboid, mostly spongy bone with a layer of compact bone on the outside.

Detailed explanation-2: -Spongy bone is composed of small needlelike or flat pieces of bone called trabeculae and has much open space.

Detailed explanation-3: -cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance.

Detailed explanation-4: -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.

Detailed explanation-5: -Spongy bone is commonly found at the end of long bones, as well as the ribs, skull, pelvic bones and vertebrae. Located in the spaces, between the trabeculae of some spongy bones is red bone marrow. Blood vessels within red bone marrow supply osteocytes of spongy bone and aid in removing waste products.
