1. _________ An example of a long bone is the femur in the leg.
2. _________ Short bones are generally made up of compact bones.
3. _________ The sternum is an example of a flat bone, which is made up of a thin layer of compact bone, around
a layer of spongy bone.
4. _________ The diaphysis is on the ends of each bone.
5. _________ The periosteum covers the sharpey’s fibers.
6. _________ The sharpey’s fibers main function is to secure the periosteum to the underlying bone.
7. _________ Articular cartilage covers the external diaphysis and decreases friction of the joint.

marrow in infants.
9. _________ Bone projections and processes grow out from the bone surface.
10. _________ Bone depressions or cavities are indentations on a bone.
11. _________ In embryos, the skeleton is made up of mostly hyaline cartilage.
