1. The superficial cervical fascia is deep cervical fascia.
2. The long thoracic nerve typically pierces the posterior scalene muscle inferior to the dorsal scapular nerve.
3. The external jugular vein is formed by the confluence of the retromandibular vein and the facial vein.
4. The interval between the heads of origin of the sternocleidomastoid muscle provides a surface landmark for accessing the subclavian artery.
5. The great auricular nerve is located posterior to the external jugular vein as both of these structures travel along the surface of the sternocleidomasoid muscle.
6. The base of the posterior triangle is defined as the first rib.
7. The transverse cervical artery crosses the posterior triangle inferior to the crossing of the suprascapular artery.
8. The spinal accessory nerve crosses the posterior triangle superior to the dorsal scapular nerve.
9. The lesser occipital nerve ascends along the anterior margin of the sternocleidomastoid muscle toward the superior apex of the posterior triangle.
10. The supraclavicular nerves share two spinal cord levels with the phrenic nerve.
