Key Questions:

1. How are the bones arranged in your head, torso, arms and legs?
   • The structure of the human skeleton: Legs: - The upper arm has one bone called the Femur. - The lower arm has two bones called the Tibia and the Fibula. The Tibia is the larger bone. - The Femur, Tibia and Fibula are connected by the Knee joint, behind the Patella (knee cap). Torso: - The Femur is connected to the Pelvis by the Hip joint. - The Spine is made up of Vertebrae connects the Pelvis to Skull. - Attached to the spine is the Rib cage and the Clavicle. Arms: - The upper arm has one bone called the Humerus. - The lower arm has two bones called the Radius and the Ulna. The Radius is on the side of the thumb. - The Humerus is attached to the Clavicle at the Shoulder joint. - Humerus, Radius and Ulna are connected by the Elbow joint.
2. What are the functions of a skeleton?
   • The functions of the human skeleton are: - support, - protection, - movement and - making blood Cells
3. What does the bone marrow do?
   • Within bones there is bone marrow which produces new blood Cells.
4. How is the movement different in a hinge, pivot, ball and socket and fixed joint?
   • There are different types of joint in the skeleton, allowing different types of movement. - Hinge: Back and forth without twisting. - Pivot: Twisting. - Ball and socket: Rotation in all directions. - Fixed: No movement
5. Give an example of a hinge, pivot, ball and socket and fixed joint.
   • The Elbow and Knee are hinge joints. The Neck, part of the spine, is a pivot joint. The Shoulder and Hip are ball and socket joints. The Skull has fixed joints in it.
