Bone Functions -Support of tissue and muscles. -Protects internal organs. -Red bone marrow produces red and white blood cells. -Calcium storage. -Efficient locomotion. -Storage of energy in yellow bone marrow. Tissues of the Skeletal System -Bone. -Compact (dense) bone is highly organized. Has concentric ring structure. -Spongy bone (cancellous) contains numerous plates separated by unequal spaces. *Spaces are often filled with red bone marrow. Tissue of the Skeletal System -Cartilage -Cartilage is flexible because the gel-like matrix contains collagenous and elastic fibers. -Three types differ according to type and arrangement of fibers. *Hyaline- Firma and flexible *Fibrocartilage- strong. *Elastic- flexible. Tissue of the Skeletal System -Fibrous Connective Tissue -Makes up ligaments (connect bone to bone) -and tendons (connect muscles to bones at joints ). Bone Growth and Repair -Several different types of cells are involved in bone growth and repair. -Osteoprogenitor cells. (bone, precursor, to produce) -Osteoblasts. (bone, germ or bud) form bone -Osteocytes. (bone, cell) -Osteoclasts. (bone, break) destroy bone Bone Development and Growth -Ossification refers to bone formation. - Intramembranous ossification - Bones develop between sheets of fibrous tissue. >Bone of the skull
