GENERAL HISTOLOGY

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 is also called trabecular bone, or spongy bone. This bone tissue is usually found at the end of long bones and inside the bones of the vertebrae. The trabeculae (truh-bek u-lee; little beams) are the small needlelike pieces of bone.

Detailed explanation-3: -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. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone.
