Its form is irregular; it is larger in size than the middle cervical ganglion, and is frequently fused with the first thoracic ganglion, under which circumstances it is then called the "stellate ganglion."


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.


The inferior cervical ganglion gives off two branches:


It is probably formed by the coalescence of two ganglia which correspond to the seventh and eighth cervical nerves.
