© 2009 Delmar, Cengage Learning Functions Support Protect Movement and anchorage Mineral storage hemopoiesis
© 2009 Delmar, Cengage Learning Structure and Formation of Bone Osteocytes –Mature bone cell Organic material (flexibility) –Collagen –Jellylike material Inorganic material (hardness and durability)
© 2009 Delmar, Cengage Learning Long Bones Shaft or diaphysis Each end is the epiphysis –Covered by articular cartilage In center is the medullary canal –Yellow bone marrow –Endosteum (lining of the marrow canal)
© 2009 Delmar, Cengage Learning Long Bones Red marrow –Ends of long bones –Manufacture red blood cells and some white blood cells Periosteum –Covering on outside of the bone
© 2009 Delmar, Cengage Learning Growth Grow in length Ossify from center outward Osteoblasts Osteoclasts
© 2009 Delmar, Cengage Learning Growth Growth stops when all the epiphyseal cartilage is ossified Females grow until about 18 years of age Males grow until about years of age

© 2009 Delmar, Cengage Learning Joints Called articulations –Points of contact between two bones Diarthroses (moveable) joints Amphiarthroses (partially movable) joints Synarthroses (immovable) joints
© 2009 Delmar, Cengage Learning Joints Articular cartilage Articular capsule –Synovial membrane –Synovial fluid –Synovial cavity Bursa sacs

© 2009 Delmar, Cengage Learning Amphiarathroses Joints Partially movable joints Cartilage between their articular surfaces Examples: –Ribs to the spine –Symphysis pubis
© 2009 Delmar, Cengage Learning Synarthroses Joints Immovable joints Connects by tough, fibrous connective tissue Example: –Adult cranium Cranial joints called sutures
