Examples arethe vertebrae and sphenoid bone.Gross anatomy of bonesEach bone contains two types of osseous tissue (bone tissue): (1) Compact bone is very denseand solid, and it is always found on the surface of the bone. (2) Spongy bone has a relativelyporous structure, and it is found in the interior of bones.keletal System: Bone Structure and Function For the next two chapters (7 and 9) we will study the skeletal system. Although the majorfeature of this system is the bones, the skeletal system also consists of cartilage, ligaments,tendons, and other structures that hold the bones together and stabilize them.
