The Skeleton And Joints Wk3 The Skeleton And Joints Wk3 Presentation Transcript

  • The Skeleton and Joints What the skeleton does
  • The Skeleton
    • The skeleton is the basic framework of the body. It has four major functions:
    • Shape
    • Movement
    • Protection
    • Blood production
    • It is important to remember that the body has other systems that support and enhance these functions as well.
    • The four major functions have a direct affect on how well or how much physical activity you can do.
  • Shape and Support
    • Without its rigid skeleton the body would have nothing to support its self on. It is the skeleton that gives each of us our own unique shape and frame.
    • The skeleton also determines size. Taller people will have longer bones then shorter people. Sturdiness (thickness of bones) can also effect people often determining overall body weight.
  • Movement
    • So how does the skeleton move?
    • Each joint has muscles either side of it, as these muscles contract (get smaller) they allow the joint to perform the movement required by the body.
    • This kind of movement is called articulation.
    • Its not just the joints that are important when moving the skeleton also provides a base for the muscles to attach.
    • Without this the muscles could not move and physical activity would be limited
  • Range of movement
    • Greatest Range of Movement
    • Shoulder
    • Elbow
    • Wrist
    • Hip
    • Knee
    • Ankle
    Green = Upper Body Red = Lower Body
  • Range of movement
    • Smaller Range of Movement
    • Hands
    • Neck
    • Spine
    • Feet
    Green = Upper Body Red = Lower Body
  • Protection
    • The skeleton also fulfils a very important role in protecting the vital soft tissue organs of the body. Most important are:
    • Rib Cage: protects the heart and lungs.
    • Pelvic Girdle: protects the abdomen
    • Spinal Column: protects the spinal chord
    • Skull : protects the brain
  • Blood production
    • The body makes blood in the bone marrow
    • Blood contains both red and white blood cells
    • The red blood cells carry oxygen to muscles, which they need in order to work
    • The white blood cells fight infection in the body.
  • Types of bones
    • There are over 200 bones in the body
    • There are over 100 joints in the body
    • Bones are divided into four main types:
    • Flat bones: the scapula, sternum, cranium, pelvis and the ribs.
    • Irregular bones: the vertebrae, patella.
    • Long Bones: bones in arms (humerus) and legs (femur).
    • Short bones: carpals and tarsals.
  • Flat Bones
    • Flat bones and irregular bones are usually protective bones.
    • The skull, ribs and pelvis protect vital organs.
  • Irregular bones
    • Bones that are not the same shape as each other.
    • The vertebrae bones and patella are good examples.
  • Long Bones
    • Long bones are the levers where the movement in the body takes place.
    • The arm contains three:
    • Humerus
    • Radius
    • Ulna
    • The leg also has three:
    • Femur
    • Tibia
    • Fibula
  • Tasks
    • Label as many bones as you know on the skeleton.
    • State next to each bone whether they are a long bones (L), irregular bone (I) or flat bone (F).
    • Work in pairs to label the rest of the skeleton.
  • Joints of the Human Body
