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of the thyroid gland has been removed, most of the carotid sheath has been cut away and the internal jugular vein has been retracted laterally.

- Trachea (pointer on first tracheal ring)
- Right lobe of thyroid gland
- Recurrent laryngeal nerve left
- Lymph vessels
- Tendon of origin of sternocleidomastoid muscle
- Common carotid artery (pointer at bifurcation)
- Thyrohyoid muscle (cut and reflected)
- Superior thyroid artery
- Vagus nerve (X)
- Longus capitis muscle
