subject #210 928 |
The superior root of the ansa cervicalis is formed by branches of spinal nerves [Cervical spinal nerve 1 (C1) and 2 (C2)].
These nerve fibers travel in the hypoglossal nerve before separating in the carotid triangle to form the superior root.
The superior root goes around the occipital artery and then descends on the carotid sheath.
It sends off branches to the superior belly of the omohyoid muscle, and the upper parts of the sternothyroid and sternohyoid muscles and is then joined by the inferior root.
