1. Bones and Joints 1

2. The Skeletal System

3. Bone is a tissue, a living material made up of cells, and is it full of capillaries. The skeletal system is made up of bones which are connected to each other by joints. Almost all bones have at least one joint. Muscles are fibres that have the ability to contract so that we can move our bodies and internal organs. All these elements make up the musculoskeletal system whose function it is to allow us to perform movement.

4. 4 types of bones based on shape

9. How many bones are there in the human skeleton? How many bones in a newborn’s skeleton? Why the difference?

10. How many bones are there in the human skeleton? 206 How many bones in a newborn’s skeleton? 270 Why the difference? During development, your bones fuse together

11. Give examples of bones that fuse during development. http://www.pennmedicine.org/encyclopedia/ em_DisplayAnimation.aspx?gcid=000112&pti d=17 http://www.pennmedicine.org/encyclopedia/ em_DisplayAnimation.aspx?gcid=000112&pti d=17

12. Where are your organs in relation to your skeletal system?

13. The Skeletal System Function – forms an internal, living framework that provides shape and support protects internal organs moves body forms blood cells stores calcium and phosphorous compounds for later use

14. Joints Definition: – Any place where two or more bones come together

15. Joints Kept far enough apart by a thin layer of cartilage so that they do not rub against each other as they move – When this happens it can cause swelling at the joint and create symptoms of arthritis. Bones are held in place at joints by a tough band of tissue called ligament

16. Types of Joints Fixed – Skull – Pelvis Semi-movable – Vertebral column Moveable – Pivot – Ball & socket – Hinge – Gliding

17. Types of Joints Ball and Socket Joint Bone with a rounded end that fits into a cuplike cavity on another bone  ex: shoulder joint: scapula to humerus http://www.shockfamily.net/skeleton/JOINTS.HTML

18. Types of Joints Pivot Joint One bone rotates in a ring of another bone that does not move  ex: radius and ulna  ex: neck joint http://www.funhousefilms.com/b-pivot2.jpg

19. Types of Joints http://www.shockfamily.net/skeleton/JOINTS.HTML Hinge Joint Back-and-forth movement like hinges on a door  ex: elbow joint (humerus into radius)

20. Type of Joints http://www.shockfamily.net/skeleton/JOINTS.HTML Gliding Joint One part of a bone slides over another bone  ex: carpals into metacarpals
