MICROANATOMY

Detailed explanation-1: -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-2: -Spongy bone is composed of small needlelike or flat pieces of bone called trabeculae and has much open space.

Detailed explanation-3: -Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones.
