Document Summary
Protection: skull is an example because it protects brain. Leverage and movement: speci cally in upper and lower extremity bones that serve as lever system in which muscles pull on bones to create movement. Storage of minerals (such as calcium and phosphorus) and lipids. Blood cell and platelet production (in red bone marrow) Various types of bone that depend on bones location, function (eg. protection, movement) Eg. humerus, femur (longest, largest, strongest), tibia, bula. Vertebra (good for pounding and distributing load, attaching ligaments and ribs, spinal cord passes through them) Good at distributing force in various directions. Patella, which changes shape of tendon attaching onto leg allowing for easier movement. Axial: main function is protection, although there is some movement. Thoracic cage, which protects lungs, heart, esophagus, stomach, liver. Some bones fuse together (eg. sacrum and skull) Sometimes people have extra bones (ie. sesamoid bones placed throughout muscles, example is fabella bone)
