The retromandibular vein and and the posterior auricular veins.
What does the external jugular vein drain into?
The subclavian vein.
What does the jugulodigastric lymph node drain?

It drains the anterior tongue.

What is the significance of the Virchow’s signal nodes?
They are right next to the thoracic duct.
Where do the visceral sensory fibers of the cervical region in CN VII, IX, and X synapse?
In the nucleus of the solitary tract (NTS).
Where are the cell bodies for motor fibers to the intrinsic laryngeal muscles that travel in CN IX and X located?
In the nucleus ambiguus.
What other cell bodies does the nucleus ambiguus contain?
It has cell bodies for parasympathetic fibers to the SA node.
What does the thyroides ima artery arise from?
The brachiocephalic trunk.
What do the superior and middle thyroid veins drain into?
