MICROANATOMY

Detailed explanation-1: -Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. It is also found inside the vertebrae, in the ribs, in the skull and in the bones of the joints.

Detailed explanation-2: -Cancellous bone, also known as spongy or trabecular bone, is one of the two types of bone tissue found in the human body. Cancellous bone is found at the ends of long bones, as well as in the pelvic bones, ribs, skull, and the vertebrae in the spinal column.

Detailed explanation-3: -The epiphysis is filled with spongy bone, which is filled with red marrow and covered by a thin layer of compact bone, with articular cartilage at the joint to prevent friction and wear. It is separated from the metaphysis by the epiphyseal plate.

Detailed explanation-4: -Spongy bone provides balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. In addition, the spaces in some spongy bones contain red bone marrow, protected by the trabeculae, where hematopoiesis occurs.
