Document Summary

Composition: bones (skeleton, cartilage (type of connective tissue composed of special cells known as chondrocytes along with collagen or yellow elastic fibers. The fibers and the cells are embedded in a firm gel like matrix rich in mucopolysaccharides. Cushions" between bones at joints. : ligaments and tendons (tendon - fibrous connective tissue which attaches muscle to bone. , ligament - fibrous connective tissue which attaches bone to bone, to promote skeletal structural stability. ) The skeletal system is broken down into 2 parts: Functions of the skeletal system: support bone is hard and rigid. Cartilage is flexible yet strong: protection skull protects brain, ribs protect heart and lungs, sternum protects breast, vertebrae protects spinal cord, movement produced by muscles on bones, via tendons. Ligaments allow some movement, but prevent excessive movement: absorb shock absorbs impact during motion to reduce strain on bone and joints and damage to soft tissues, storage stores calcium and phosphorous.
