Presentation Transcript

  1. Lecture 6.6: Skeletal System

  2. Cervical Vertebrae • Atlas-C1 • Holds up head • Allows “yes” motion • Axis—C2 • “No” motion

  3. Figure 6.18

  4. Lumbar Vertebrae • Most massive • Least mobile • Support most of body weight

  5. Figure 6.17c

  6. Thoracic Cage • Thoracic vertebrae, ribs and sternum • Protects heart and lungs

  7. Ribs • 12 pairs • True Ribs—first 7 pairs • Connect to sternum via costal cartilage • False ribs—pairs 8-12 • Do not directly attach to sternum • Floating ribs—pairs 11-12 • No connection to sternum

  8. Figure 6.20b

  9. Sternum • Breastbone • Not fully fused until 25 • Xiphoid process—inferior tip

  10. Figure 6.20a
