ANATOMY

Detailed explanation-1: -Spongy Bone (Cancellous Bone) Spongy bone is supplied by fewer and larger vessels than compact bone. These vessels perforate the outer compact layer and are distributed into the spongy portion of bone, which is filled with marrow.

Detailed explanation-2: -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. Compact tissue is also known as hard bone, compact bone or compact cortical bone.

Detailed explanation-3: -Cancellous bone is also defined as spongy bone or trabecular bone. It got the name spongy bone because cancellous bone is porous under the microscope.

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.
