THE CRANIAL EXTREMITIES OF THE SYMPATHETIC TRUNKS

Abstract

It is suggested that the true cranial extremities of the trunci sympathici are within the skull and coalesce around the arteria communicans "anterior in a cranial ganglion impar, and that the nervi et plexus caroticus internus, with their contained groups of discrete ganglion cells, are not branches of distribution of the ganglion cervicale superius but are the cephalic part of the truncus sympathicus.
