The ansa cervicalis (or ansa hypoglossi in older literature [citation needed]) is a loop formed by muscular branches of the cervical plexus formed by branches of cervical spinal nerves C1-C3. The ansa cervicalis has two roots - a superior root (formed by branch of C1) and an inferior root (formed by union of branches of C2 and C3) - that unite ...
ansa cervicalis [1]: 546, 576, 578 (usually embedded within the anterior wall of the carotid sheath anterior to the internal jugular vein; [7] the superior root of ansa cervicalis is situated either anterior to or within the carotid sheath [1]: 595 ), deep cervical lymph nodes [4]: 148 [8] [2] [1]: 593
It is a part of the ansa cervicalis along with the C1 and C3 nerves sometimes forming part of superior root of the ansa cervicalis. [2] it also connects into the inferior root of the ansa cervicalis with the C3. [2] It originates from the spinal column from above the cervical vertebra 2 (C2).
The thyrohyoid branch [1] (also: thyrohyoid branch of ansa cervicalis, [2] or nerve to thyrohyoid (muscle) [2] [3]: 595, 600 ) is a motor branch derived from the cervical plexus [2] [2] [3]: 595, 600 [4]: 457, 709 formed by fibres of (the anterior ramus of [3]: 600 ) the cervical spinal nerve 1 (C1) [3]: 582 [5] [6] [4]: 457, 709 (and - according to some sources - cervical spinal nerve 2 (C2 ...
Superficial to the carotid sheath lies the hypoglossal nerve, and ansa cervicalis of the cervical plexus. The hypoglossal nerve crosses both the internal and external carotids, curving around the origin of the occipital artery. Within the sheath, between the artery and vein, and behind both, is the vagus nerve; behind the sheath, the ...

A nerve plexus is a plexus (branching network) of intersecting nerves. [1] A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels.
