The major nerves leaving from the cervicothoracic ganglion were vertebral nerve, two branches forming subclavian ansa (cranial and caudal branches) and thin nerve branches originating from the caudodorsal and caudoventral sides of ganglion.
Caudal branch forming subclavian ansa gave nerve branches to vagus nerve.
Besides these branches, caudal vertebral cardiac nerves are separated from this ganglion as well as cranial and caudal branches which form subclavian ansa and vertebral nerve (Getty, 1975; Dursun, 2000; Pather et al.
1,2-f) which formed subclavian ansa was separated from cranioventral side of the ganglion; 1 or 2 thin nerve branches were diverged from caudodorsal (Figs.
These nerves known as cranial and caudal branches of subclavian ansa were originated from cranioventral and ventral sides of cervicothoracic gangion, respectively.
Generally 2 to 3 branches were originated from ventral side of cervicothoracic ganglion except caudal branch of subclavian ansa.
In the goat, same researcher (Getty, 1975) has specified that middle vertebral ganglion has located after vertebral ganglion and vertebral ganglion is on the combination point of two branches of subclavian ansa.
2009) that nerve branches radiated out from cervicothoracic ganglion are the vertebral nerve, cranial and caudal branches that form subclavian ansa, caudal vertebral cardiac nerves.
