    1. 1. The Skeletal System By Patricia Rojas and Carly Schwartz Image from:http://homes.bio.psu.edu/people/faculty/strauss/anatomy/skel/skeletal.htm
    2. 2. Function <ul><li>Protects many organs </li></ul><ul><li>Forms the shape of the body </li></ul><ul><li>Provide support for the body </li></ul><ul><li>Provides locomotion </li></ul>Overview Video: http://www.youtube.com/watch?v=C2dTbJDQ3u0&feature=related Picture taken from Neil Campell’s Biology: Concepts and Connections. 6th ed
    3. 3. Bone Structure <ul><li>Made of calcium, phosphorous,and sodium </li></ul><ul><li>Types </li></ul><ul><ul><li>Compact bone </li></ul></ul><ul><ul><li>Cancellous bones </li></ul></ul><ul><li>Perostium </li></ul><ul><li>Bone marrow </li></ul>Image from: http://kidshealth.org/parent/fitness/general/bones_muscles_joints.html
    4. 4. Haversian Canals <ul><li>Within compact </li></ul><ul><ul><li>bone </li></ul></ul><ul><li>A long cylinder in which blood vessels flow </li></ul><ul><li>through </li></ul>Image from: http://www.bcb.uwc.ac.za/Sci_Ed/grade10/mammal/bone.htm
    5. 5. Movement <ul><li>Three types of joints </li></ul><ul><ul><li>Hinge joints </li></ul></ul><ul><ul><li>Pivot joints </li></ul></ul><ul><ul><li>Ball-to-socket joints </li></ul></ul>Picture taken from Neil Campell’s Biology: Concepts and Connections. 6th ed
    6. 6. How the system works! <ul><li>Cartilage -> thick strong </li></ul><ul><li>bones </li></ul><ul><li>Fastened together </li></ul><ul><li>by ligaments </li></ul><ul><li>Muscles move bones </li></ul><ul><li>attached by tendons </li></ul><ul><ul><li>Connect at joints </li></ul></ul>Image from: http://kidshealth.org/parent/fitness/general/bones_muscles_joints.html
    7. 7. How the system is regulated <ul><li>Osteoblasts - makes new bones and repairs bones </li></ul><ul><li>Osteoclasts - sculpt and reshape bones </li></ul><ul><li>Osteocytes - sends signals to other cells </li></ul>Images from: http://www.womentowomen.com/bonehealth/natureofhealthybones.aspx
    8. 8. Interactions with other body systems <ul><li>Muscular system </li></ul><ul><ul><li>Movement </li></ul></ul><ul><ul><ul><li>Contracting and relaxing </li></ul></ul></ul><ul><li>Skeletal muscles </li></ul><ul><ul><li>Interact with bones </li></ul></ul><ul><ul><li>Hold skeleton together </li></ul></ul>Image from: http://www.free-ed.net/sweethaven/science/biology/anatomyphysiol/Human01_LessonMain.asp?iNum=0402
    9. 9. Interactions with other body systems <ul><li>Circulatory system </li></ul><ul><ul><li>Bone marrow makes white and red blood cells </li></ul></ul><ul><ul><li>Blood cells travel through bones </li></ul></ul><ul><ul><li>Blood=oxygen and nutrients to bones </li></ul></ul><ul><ul><li>Ribs protect lung and heart </li></ul></ul>
    10. 10. Osteosarcoma <ul><li>Causes: </li></ul><ul><ul><li>DNA mutation </li></ul></ul><ul><ul><li>radiation therapy </li></ul></ul><ul><li>Common in children and men </li></ul><ul><li>Treatments: </li></ul><ul><ul><li>Surgery, chemotherapy, </li></ul></ul><ul><ul><ul><li>radiation therapy, cryosurgery </li></ul></ul></ul>Image from: http://www.mayoclinic.org/osteosarcoma/treatment.html
