Features of Bone Projections that form joints Features of Bone Projections that form joints Projections that are sites of muscle & ligament attachment Features of Bone Projections that form joints Projections that are sites of muscle & ligament attachment Openings that allow blood vessels and nerves to pass Features of Bone Projections that form joints Projections that are sites of muscle & ligament attachment Openings that allow blood vessels and nerves to pass Depressions

21. Structure of Bone

22. Bone Development & Growth Two Categories of Bone Development 1.Intramembranous (Direct) – forms spongy bone and eventually may form compact bone from embryonic fibrous membrane 2.Endochondral - bone forms from cartilage; forms skull & flatbones Before week 8 of fetal life, the human skeleton is all fibrous membrane & hyaline cartilage
