THE NERVE SYSTEM 



auricular branch of the facial, and is distributed to the integument behind the 



ear. 



The Superficial or Transverse Cervical Nerve (n. cutaneus colli) (Fig. 754) arises 

 from the second and third cervical nerves, turns around the posterior border of 

 the Sternomastoid about its middle, and, passing obliquely forward beneath the 

 external jugular vein to the ventral border of the muscle, perforates the deep 

 cervical fascia, and divides beneath the Platysma into two branches, which are 

 distributed to the antero-lateral parts of the neck.

 has been partly removed. (Spalteholz.) 



The ascending branch (ramus superior} gives a filament which accompanies the 

 external jugular vein; it then passes upward to the submaxillary region, and divides 

 into branches, some of which form a plexus with the cervical branches of the 

 facial nerve beneath the Platysma; others pierce that muscle and are distributed 

 to the integument of the upper half of the neck, at its fore part, as high as the chin. 



The descending branches (rami inferiores], usually represented by two or more 

 filaments, pierce the Platysma, and are distributed to the integument of the side 

 and front of the neck, as low as the sternum.
