  1. The Joints and Movement Mr N Smith - WBHS What Price? The risk of injury through dislocation.

  2. Ligaments ................ Join bone to bone for stability Capsule .................... Provides stability and protection from infection Cartilage ................... Reduce wear and tear on bones Synovial Fluid ........... Lubricates the joint and provides shock absorption Synovial Membrane .. Produces synovial fluid

  3. Hinge - Two bones join in such a way that movement is only possible in one direction e.g. elbow Types of Synovial Joints • Ball and Socket - A ball shaped bone fits into a socket shaped bone. Lots of movement e.g. Shoulder, hip • Pivot - A joint constructed in such a way that rotation only is possible e.g. atlas and axis (top vertebrae) • Condyloid- Also known as ellipsoid joint. e.g. Carpals and radius • Gliding- Bone surfaces are small and flat and slide over each other e.g. scaplua and ribs

  4. Movements at Synovial Joints Bending over or sideways Bending or decreasing the angle between two bones about a joint. Bringing the arm forward Bending at the elbow Palm to forearm Raising the thigh Bending the knee

  5. Straightening or bending back Straightening or increasing the angle between two bones about a joint. Moving the arm backwards Straightening the elbow Straightening the wrist Moving the leg backwards Straightening the knee

  6. Moving a limb or part of a limb AWAY from the midline of the body. Star - jump Moving a limb or part of a limb BACK TOWARDS the midline of the body. Bringing limbs back in from a star –jump.

  9. Movement of the hand so the palm is face UP. Opening a door with a door knob. Movement of the hand so the palm is face DOWN. Turning a card face down.

  10. Twisting of a limb or body part along its long axis. Turning the head or twisting the arm. A combination of flexion, extension, abduction and adduction. Shape of a cone. The arm action In butterfly.

  11. Femur & Tibia Flexion Ulna & Radius Extension Scapula & Humerus Flexion Femur & Pelvis Extension Tibia, Fibula, Tarsals Plantarflexion Femur and Tibia Extension Carpals, Radius, Ulna Flexion
