lips, including the upper teeth 

 and the inferior maxillary, 

 sending its branches to the 

 tongue, cheekss, and anterior 

 portion of the face. 



588. Abducentes. — The 

 sixth pair, abducentes , are sent 

 from the medulla oblongata to 

 the external muscle of the eye. 



589. Facial.— The facial 

 nerves have their origin in 

 common with the last pair. 

 They join with some of the 

 branches of the fifth pair, and 

 distribute their filaments to 

 some of the muscles of the face. 



590. Auditory —The au- 

 ditory nerves, as their names 

 imply, are sent to the ear. 

 They enter the internal ear
