Accessory Nerve (CN XI) – runs on superficial surface of levator scapulae muscle


Phrenic Nerve (C3, 4, & 5) – runs on superficial surface of anterior scalene muscle
Vagus Nerve (CN X) – runs in sheath with common carotid artery and internal jugular vein

Cervical Plexus – “You may want to be able to draw this structure.” – Dr. Cook



Motor Nerves = Dark Green

Sensory Nerves = Orange

In the lecture Dr. Cook pointed out on this slide that often the Dorsal Scapular Artery runs into the Transverse

Cervical Artery and they become a single artery.




Dr. Cook is stressing muscle attachment sites and actions. Be sure to look at both in your note packets.
Also, anatomical landmarks are HUGE in head and neck so be sure to know where things attach and go to.


50% of the rotation of the head (cervical rotation) from side to side comes from rotation at the junction of the

C1 and C2 vertebrae (the atlas and the axis – aka the Atlantoaxial Joint)



- Most of this rotation is achieved by the Inferior Oblique Muscle
The Posterior Arch of C1 (the Atlas) is visible in the deep portion of the Suboccipital Triangle
Note the Greater Occipital Nerve wrapping around the inferior border of the Inferior Oblique Muscle
