Presentation Transcript

  1. Agenda: • Bones of the Axial Skeleton Continued

  2. Vertebral Column Double curvature of the spine - adaptation for upright posture C1 = atlas C2 = axis C1 – C7 = cervical vertebrae T1 – T12 = thoracic vertebrae L1 – L5 = lumbar vertebrae

  3. Page 219 – Draw and label a vertebra

  4. Please know: • Superior articular process • Inferior articular process • Vertebral body • Spinous process • Transverse process

  5. How to distinguish between vertebrae types Cervical Thoracic Lumbar smaller, more larger, U body,largest, doesflexible, bifid shape, rigid, not articulateprocess, narrow articulates with with ribs, largenerve passage, the ribs, medium nerve passage,no rib articulation, nerve passage circular body oval body shape shape (oval)

  6. Sacrum & Coccyx

  7. Thoracic Cage True ribs (pairs 1 – 7) False ribs (pairs 8 – 12) Floating ribs (pairs 11 – 12) Parts of Sternum: • Manubrium • Body • Xiphoid Process
