Thyrohyoid branch

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) as well^{[2][4]: 457, 709}) that join and travel with the hypoglossal nerve (cranial nerve XII)^[5] to reach the suprahyoid region,^[2] branching away from CN XII distal to the superior root of ansa cervicalis^{[3]: 582 [4]: 709 [6]} (which is a branching other fibres of C1-C2 that had traveled with the CN XII^[4]: 709), near the posterior border of the hyoglossus muscle.^[3]: 600 The thyrohyoid branch of ansa cervicalis innervates the thyrohyoid muscle.^{[2][6][3]: 582 [4]: 457, 709}
