 nerves (Held) : Schematically lepresented in a supposedly transparent brain stem viewed 

 from behind. (Nuclei and roots of motor nerves in light red, of sensory nerves in 

 purple. Cochlear nerve in yellow.) 4, nucleus of the third nerve (n. oculomotorii);

 nerve; 14, nucleus of the sixth cranial nerve; 15, nucleus of the facial (seventh) 

 nerve; 16, the facial nerve; 34, 33, nucleus of the vestibular branch of the eighth cranial 

 nerve; 32, ventral nucleus of the cochlear branch of the eighth nerve; 27, dorsal nucleus 

 of the cochlear branch of the eighth nerve; 19, 29, the glossopharyngeal nerve; 18, 28, the 

 vagus nerve; 20, motor nuclei of vagus and glossopharyngeal (nucleus ambiguus and 

 nucleus dorsalis); 23, 24, nucleus of the alse cinerese, the solitary bundle and its nucleus; 

 17, the eleventh or spinal accessory nerve; 22, nucleus of the spinal accessory; 21, nucleus
