Dissection of anterior and lateral regions of neck
Left common carotid artery, vagus nerve and thoracic duct, anterior view
The left lobe of the thyroid gland has been removed, most of the carotid sheath has been cut away and the internal jugular vein has been retracted laterally.

  2. Thyroid cartilage
  3. Upper pointer: Sternocleidomastoid muscle (cut across) Lower pointer: External jugular vein
  4. Internal jugular vein (within carotid sheath)
  5. Cricoid cartilage
  6. Omohyoid muscle
  7. Trachea (pointer on first tracheal ring)
  8. Right lobe of thyroid gland
  9. Recurrent laryngeal nerve left
  10. Lymph vessels
  11. Tendon of origin of sternocleidomastoid muscle
  12. Common carotid artery (pointer at bifurcation)
  13. Thyrohyoid muscle (cut and reflected)
  14. Superior thyroid artery
  15. Vagus nerve (X)
  16. Longus capitis muscle
  17. Internal jugular vein
  18. Upper pointer: Middle cervical ganglion Lower pointer: Ascending cervical artery
  19. Anterior scalene muscle
  20. Middle scalene muscle
  21. Inferior cervical ganglion
  22. Brachial plexus (cut across distal to trunks)
