Trabecular Bone Constitutes the Internal Cavity of the Bone

Trabecular bone is a type of bone tissue that forms the inner cavity of the bone. It is more porous and lighter than compact bone. Also, long bones contain trabecular bone at their enlarged ends. In addition, trabecular bone is the main component of the ribs, as well as the shoulders and the flat bones of the skull. Most of the short straight bones of the skeleton are also composed of trabecular bones.
