Peripheral Nervous System in Human Embryo 301 



The cardiac plexus and the cranial sympathetic ganglia owing to the 

 more complicated architecture of those regions could not be outlined 

 with any accuracy. The cephalic end of the ganglionated cord can be 

 traced median to the hypoglossal nerve to the region situated between 

 the ganglion nodosum and the wall of the pharynx. Its extension along 

 the internal carotid artery and commuication with the ganglia of the 

 head could not be made out.
