1. Year 10 PE Knowledge OrganiserTopic 1.1: Applied Anatomy & PhysiologyFUNCTIONS OF THE SKELETONTHE SKELETONJOINTSSUPPORT - The skeleton supports the muscles.PROTECTION - The skeleton protects delicate parts of the body like the brain.MOVEMENT - Muscles are attached to the bones and once contracting allows movement.POSTURE - The skeleton gives us our shape/size and helps us remain upright.BLOOD CELL PRODUCTION - vital minerals such as calcium and phosphorus are stored in bones. STORAGE OF MINERALS - blood cells are made in the bone marrow.FLEXION - bending a jointEXTENSION – straightening a jointABDUCTION - movement away from the midline of the bodyADDUCTION - movement towards the midline of the bodyCIRCUMDUCTION - where the limb moves in a circleROTATION - where the limb turns round its long axisHINGE JOINTSKNEE & ELBOW TYPES OF MOVEMENTBALL & SOCKET JOINTSSHOULDER & HIP CONNECTIVE TISSUELIGAMENTS – ATTACH BONE TO BONETENDONS – ATTACH MUSCLE TO BONECARTILAGE – A RUBBER-LIKE PADDING THAT COVERS AND PROTECTS THE ENDS OF LONG BONESTHE MUSCLESANTAGONISTIC MUSCLE ACTIONLEVERSPLANES AND AXES OF MOVEMENTA plane is an imaginary flat surface running through the body.An axis is an imaginary line at right angles to the plane, about which the body rotates or spins
