In fig. 4 the maxillo-mandibular ganglion sends its first branches 

 {max.) cephalad and mesad to supply muscles and the lining of 

 the roof of the mouth cavity. Motor and sensory fibers seem to 

 be intermingled. The root of the velar nerve {y.n.) is turning 

 ventro-caudad and lies on the mesal surface of the ganglion. 

 Behind it is the pure motor root of coarse fibers [man.). The so- 

 called VI nerve enters the posterior rectus muscle in this section.

The VII nerve gives ofi^ a large branch caudad which is the root of 

 the sympathetic trunk. The IX and the first division of the X nerve 

 each send mesad a visceral ramus (r.v.), the main trunk of the 

 nerve continuing down as before. 



Fig. 5 shows two large maxillary rami going forward. The 

 mesal one is motor, the lateral goes directly forward to the dorsal 

 and anterior surface of the buccal funnel and is chiefly or wholly
