Transcript

  • 1. Principles of Anatomy and Physiology in Sport Session 3 – The Skeletal System
  • 2. Re-Cap Last Session
    • Functions of skeletal system – Name the 6??
    • Bone structure – components??
  • 3. Functions of the Skeleton 3. Blood Production Red blood cells are made in the ribs and limb bones. 1.Protection The rib cage protects the delicate heart and lungs. 6. Movement The bones and joints work with muscles to enable us to walk, run and sprint. 5. Support The vertebrae support the head. 4. Calcium Storage Bone is the largest supply of calcium 1. Protection The cranium protects the soft tissue of the brain. 2. Shape Without the skeleton, the body would be flabby and shapeless.
  • 4. Bone Structure
    • Compact Bone
      • Found at the shaft or diaphysis of long bones
      • External layer of bone that copes with the stresses of PA
    • Cancellous Bone
      • Referred to as the spongy part of a bone
      • Found under the external layer of compact bone
      • Bone marrow is found in this part of the bone
  • 5.
    • Aim
    • To complete assignment 1
    • Objectives
    • To be able to identify and describe each classification of bone
    • To be able to link the function a bone to a specific classification
    Aims & Objectives
  • 6. Activity
    • With your partner work together to list and briefly describe the 5 classifications (types) of bone
  • 7. Bone Classification
    • There are 5 different types of bone, which are classified according to their shape, size & function
      • Long
      • Short
      • Flat
      • Irregular
      • Sesamoid
  • 8. Classification of Bones Bones are classified according to their function.
    • (Protection/calcium storage) FLAT BONES
    • (Protection) IRREGULAR BONES
    • (Levers/blood cell production) LONG BONES
    • SHORT BONES
    • SESAMOID
    .
  • 9. Activity
    • Individually think back to the previous session and try to give 3 examples of bone for each classification e.g. long bone - femur
  • 10.  
  • 11. Bone Classification Patella Vertebrae Coccyx Cranium Scapular Clavicle Pelvis Sternum Ribs Facial Bones Tarsals Carpals Metatarsals Metacarpals Phalanges Humerus Ulna Tibia Fibula Radius Femur Sesamoid Irregular Flat Short Long Types of bone
  • 12. Short Bone
    • Consists mainly of cancellous bone surrounded by a thin outer layer of compact bone, e.g. metacarpals
    • Often used in fine movement
  • 13. Flat or Plate Bones
    • Consists of 2 outer layers of compact bone between which is a layer of cancellous bone
    • Provide protection to internal organs, most importantly the brain
    • Allow for muscle attachments , e.g. scapula
  • 14. Irregular & Sesamoid Bones
    • Irregular
      • 2 outer layers of compact bone with cancellous bone between them
      • Complex in shape, e.g. vertebrae. Vertebral column provides movement, protection of the spinal cord and support for muscles of the back
    • Sesamoid
      • Bones that are embedded in tendons, e.g. patella
  • 15. Summary
    • 5 classifications of bone
    • Functions of each classification
  • 16. Objectives
    • To be able to identify and describe each classification of bone
    • To be able to link the function of a bone to a specific classification
  • 17. Next Session
    • Assignment 1!!!
