Posterior cervical region and suboccipital muscles dissected from behind

Superficial structures of back of neck; cervical fascia; trapezius muscle

On the side of the neck the superficial or investing layer of cervical fascia has been preserved together with the nerves, blood vessels and lymph nodes that lie external to it. On the right the trapezius and sternocleidomastoid muscles have been exposed by removing this fascia

1. Occipital belly of occipitofrontal muscle
2. Greater occipital nerve
3. Third occipital nerve
4. Lesser occipital nerve
5. Retroauricular lymph node
6. Occipital lymph node
7. Sternocleidomastoid muscle (covered by cervical fascia)
8. Medial branch of dorsal branch cervical nerve IV
9. Third occipital nerve right
10. Trapezius muscle (pointer near origin from superior nuchal line)
11. Sternocleidomastoid muscle (pointer near insertion into superior nuchal line)
12. Aberrant muscular slip
13. Posterior cervical triangle
14. Trapezius muscle (origin from nuchal ligament)
15. Spinous process vertebra C. VII
16. Dorsal branch cervical nerve VII
