 VII and VIII nerves and behind the capsule the nerves spinal

In fig. 3 the optic nerve enters the eyeball. The trigeminus 

 appears in three parts, at the anterior border the velar nerve, in 

 the mesal portion the coarse fibered motor root, and in the lateral

 this and the auditory capsule lies the ganglion of the neuromast 

 division of the VII nerve. Lateral to this is the so-called VI
