Document Summary

Intro image is fetal development of the bone. A lot of the bones in the body start as cartilage, we make a cartilage skeleton that becomes mineralized/ossified/calcified (these are all interchangeable. Support: main compoents for supporting the body tissues, bone. Supports the soft tissues of the body (without it, we"re sloppy) is hard and ridged but its not rock- it"s a complex and dynamic tissue, its constantly changing. Bone is constantly being broken down and rebuilt throughout the life span. Bone is the strongest tissue in the body: cartilage, ligaments. Less strong than bone but more flexible than bone. Flexibility of cartilage depends on the type that it is. Has a lot of characteristics similar to bone. Hold 2 bones together in a joint. Protects soft tissues of the brain: ribs, sternum, vertebrae. Protect all of the thoracic cavity organs. Vertebrae creates the canal that protects the spinal column.
