Detailed explanation-1: -Short bones are roughly cube shaped with vertical and horizontal dimensions approximately equal. They consist primarily of spongy bone, which is covered by a thin layer of compact bone . Short bones include the bones of the wrist and ankle.
Detailed explanation-2: -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.
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.
Detailed explanation-4: -Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.
