Stellate Ganglion

The stellate ganglion is a sympathetic nerve ganglion located in the base of the neck, right behind the vertebral artery. Being part of the sympathetic ganglionic chain, it originates through the merging of the inferior cervical ganglion and the first thoracic ganglion, which are joined together by the loop of Vieussens. Although it is usually present in most individuals, others do not have this ganglion.

From the stellate ganglion comes off the inferior cardiac nerve, which is a sympathetic nerve that works as a heart rate accelerator, being part of the cardiac plexus.
