downward course before passing distally to their ultimate splanchnic distribution. 

 The white fibres are either spinal splanchnic efferent or afferent fibres. 



The branches of distribution from the gangliated cord include the somatic 

 and the visceral. The somatic branches are the gray rami communicantes ; the 

 visceral branches comprise the splanchnic efferents, which consist of both white 

 and gray efferent fibres, as well as the white splanchnic afferents. 



THE CERVICO-CEPHALIC PORTION OF THE GANGLIATED CORD. 



The cervico-cephalic portion of the gangliated cord (pars cephalica et cervicalis 

 systematis sympathetic!) consists of a series of ganglia, usually three, but often only 

 two, connected by composite association cords (Fig. 1131). It lies posterior to the
