book and compare this with the findings in the cadaver. 

 Study the mode of formation of the cavum Meckelii. Ex- 

 amine the three great trunks: 



(aa) Ophthalmic nerve (N. ophthalmicus). 



(ab) Maxillary nerve (N. maxillaris) (0. T. superior maxillary).

Do these trunks arise from the convexity or 

 from the concavity of the ganglion? With which 

 is the motor root (portio minor) combined? Find 

 the following branches of the N. ophthalmicus :
