The '''superior cervical ganglion''' (SCG), the largest of the cervical ganglia, is placed opposite the second and third [[cervical vertebræ]]. It contains [[neuron]]s that supply [[sympathetic nervous system|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]].
