The superior cervical ganglion (SCG), the largest of the cervical ganglia, is placed opposite the second and third cervical vertebræ. It contains neurons that supply sympathetic innervation to the face.
It is of a reddish-gray color, and usually fusiform in shape; sometimes broad and flattened, and occasionally constricted at intervals; it is believed to be formed by the coalescence of four ganglia, corresponding to the upper four cervical nerves.
The superior cervical ganglion lies anterior to the sheath of the internal carotid artery and internal jugular vein, and posterior to the Longus capitis muscle.
It receives input from the ciliospinal center.
