It is probably formed by the coalescence of two ganglia which correspond to the seventh and eighth cervical nerves.
It is connected to the middle cervical ganglion by two or more cords, one of which forms a loop around the subclavian artery and supplies offsets to it. This loop is named the ansa subclavia (Vieussenii).
The ganglion sends gray rami communicantes to the seventh and eighth cervical nerves.
It gives off the inferior cardiac nerve, and offsets to bloodvessels.
Inferior cardiac nerve
Offsets to bloodvessels
The offsets to bloodvessels form plexuses on the subclavian artery and its branches.
The plexus on the inferior thyroid artery accompanies the artery to the thyroid gland, and communicates with the recurrent and external laryngeal nerves, with the superior cardiac nerve, and with the plexus on the common carotid artery.
