4. FUNCTION Bones support and protect organs Gives shape and structure

5. SKELETON
Axial –the skull, face, vertebral column, and rib cage (80 bones)
Protection

6. SKELETON Appendicular –the arms and legs, pelvis, scapula, etc
(126 bones)
Movement

7. BONE STRUCTURE Porous and made of proteins and minerals
osteocytes –cells that make bone
bone marrow – soft bone tissue that produces blood cells

ossification: hardening of bone cartilage
Elongation at end of bones

9. JOINTS
Place where two bones meet

10. Associated Connective Tissue
Ligaments: connects bone to bone
(tough bands that hold joint in place)
Tendons: connect muscle to bone
Cartilage: flexible connective tissue
