Superior cervical ganglion
|Nerve: Superior cervical ganglion (SCG)|
|Diagram of the cervical sympathetic. (Labeled as "Upper cervical ganglion")|
|Latin||ganglion cervicale superius|
|Gray's||subject #216 978|
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.
It receives input from the ciliospinal center.
