  1. 1. Anatomy and Physiology Musculoskeletal System Version 1 17/11/09 Document Title (Editable via ‘Slide Master’) | Page 1
  2. 2. The Skeletal System Prefix : oste/o – referring to bone Document Title (Editable via ‘Slide Master’) | Page 2
  3. 3. The adult human skeleton has 206 named bones Document Title (Editable via ‘Slide Master’) | Page 3

  8. 8. Joints Joints are the place where two bones meet. All of your bones, except for one (the hyoid bone in your neck), form a joint with another bone. Joints hold your bones together and allow your rigid skeleton to move. Document Title (Editable via ‘Slide Master’) | Page 8
  9. 9. Fixed Joints Some of your joints, like those in your skull, are fixed and don't allow any movement. The bones in your skull are held together with fibrous connective tissue. Document Title (Editable via ‘Slide Master’) | Page 9

  11. 11. Slightly Movable Joints Other joints, such as those between the vertebrae in your spine, which are connected to each other by pads of cartilage, can only move a small amount. Document Title (Editable via ‘Slide Master’) | Page 11
  12. 12. Document Title (Editable via ‘Slide Master’) | Page 12
  13. 13. Synovial Joints Most of your joints are 'synovial joints'. They are movable joints containing a lubricating liquid called synovial fluid. Synovial joints are predominant in your limbs where mobility is important. Ligaments help provide their stability and muscles contract to produce movement. The most common synovial joints are: Document Title (Editable via ‘Slide Master’) | Page 13
  14. 14. Ball & Socket are the most mobile type of joint in the human body. They allow you to swing your arms and legs in many different directions. Document Title (Editable via ‘Slide Master’) | Page 14
  15. 15. Document Title (Editable via ‘Slide Master’) | Page 15
  16. 16. Ellipsoidal joints allow bending and extending, rocking from side to side, but rotation is limited. Document Title (Editable via ‘Slide Master’) | Page 16
  17. 17. Document Title (Editable via ‘Slide Master’) | Page 17
  18. 18. Gliding Joints occur between the surfaces of two flat bones that are held together by ligaments. Document Title (Editable via ‘Slide Master’) | Page 18
  19. 19. Document Title (Editable via ‘Slide Master’) | Page 19
  20. 20. Hinge Joints enable movement similar to the opening and closing of a hinged door. Document Title (Editable via ‘Slide Master’) | Page 20
  21. 21. Document Title (Editable via ‘Slide Master’) | Page 21
  22. 22. Pivot Joint Allows movement on one plane only in a pivot fashion Document Title (Editable via ‘Slide Master’) | Page 22
  23. 23. Document Title (Editable via ‘Slide Master’) | Page 23
  24. 24. Saddle Joint The bones in a saddle joint can rock back and forth and from side to side, but they have limited rotation. Document Title (Editable via ‘Slide Master’) | Page 24

  26. 26. Document Title (Editable via ‘Slide Master’) | Page 26
  27. 27. Ligaments: Tendons: connect bone to bone connect bone to muscle Document Title (Editable via ‘Slide Master’) | Page 27
  28. 28. Common Disorders •OSTEOARTHRITIS – Degeneration of joints causing pain, stiffness and limited movement. Document Title (Editable via ‘Slide Master’) | Page 28
  29. 29. •OSTEOMALACIA – Softening of the bones due to a deficiency of Vitamin D. Document Title (Editable via ‘Slide Master’) | Page 29
  30. 30. •OSTEOPOROSIS – Decrease in bone mass producing a porous skeleton. Document Title (Editable via ‘Slide Master’) | Page 30
