  1. The Neck:Musculature and Bony Anatomy

  2. Bony Framework • 7 cervical vertebrae • Atlas (C1) • Axis (C2) • C3 - C7

  3. Atlas • 1 – Articular process • 2 – Transverse process • 3 – Posterior arch

  4. Axis • 1 – Dens/Odontoid process • 2 – Spinous process

  5. Cervical Vertebra • 1 – Transverse foramen • 2 – Body • 3 – Vertebral foramen • 4 – Transverse process • 5 – Spinous process • 6 – Articular process

  6. Palpation of bony anatomy • Spinous process; vertebra prominens (C7) • Transverse process

  7. Palpation of Bony Anatomy • Hyoid bone • Clavicle • Thyroic cartilage • Cricoid cartilage

  8. Intervertebral Discs • Annulus fibrosus • Nucleus pulposus • Shock absorbers for spine

  9. Nerves of the Cervical Spine • 7 vertebrae, but 8 nerves • Emerge above corresponding vertebra, except C8 nerve • Brachial plexus – C5-T1 • Myotomes and Dermatomes

  10. Muscles of the Neck

  11. The Neck:Common Injuries and Problems

  12. Pain Generators • Myogenic • Discogenic • Facet joint, Arthritic • Stenotic (central canal, neuroforamen) • Neurogenic
