(aa) Middle meningeal nerve (N. meningeus [medius]) (0. T. 



recurrent). 



This has been studied already within the cranium. 



(ab) Zygomatic nerve (N. zygomaticus) (0. T. orbital or temporo- 



malar). 



Already studied, with its two rami, in the orbit, 

 .(ac) Sphenopalatine nerves (Nn. sphenopalatini) , going to the 

 ganglion sphenopalatinum. 



(ad) Superior alveolar nerves (Nn. alveolares superiores). 



(ada) Posterior superior alveolar rami (rami alveolares 

 superiores posteriores) (0. T. posterior superior 

 dental). 



(ae) Infraorbital nerve (TV. infraorbitalis). 



(aea [also adb]) Middle superior alveolar ramus (ramus 

 alveolaris superior medius) (0. T. mid- 

 dle superior dental). 



(aeb [also adc]) Anterior superior alveolar rami (rami 

 alveola? 3 s superiores anteriores) (0. 

 T. anterior superior dental). 

 How is the superior dental plexus (plexus den- 

 dentalis superior) formed? Find 



(1) Superior dental rami (rami dent ales supe- 



riores). 



(2) Superior gingival rami (rami gingivales 



superiores). 



The other terminal rami of the infraorbital nerve have been 

 studied in the dissection of the face. 

 (b) Infraorbital artery (A. infraorbitalis). 



Its origin has already been studied. Examine its course 

 and 



(ba) Anterior superior alveolar arteries (Aa. alveolares superiores 

 anteriores) (0. T. anterior superior dental). 



SAGITTAL SECTION OF FOREPART OF HEAD NEAR 

 MEDIAN PLANE. 



Remove the mandible, with the tongue and larynx, by making 

 a cut backward from the angle of the mouth through the cheek, 

 the raphe pterygomandibularis, and the lateral wall of the phar- 

 ynx. Cut through also the vessels and nerves still connecting 

 the pharynx with the skull. Wrap the larynx and tongue in 

 moist cloth for subsequent dissection. 



Make a sagittal saw-cut through the forepart of the skull 

 just lateral from the septum nasi; if the septum is not vertical, 

 but deviates somewhat to one side, make the section close to the 

 concave side of the septum. Before sawing, cut through the 

 cartilaginous part of the nose as far as the nasal bone with a
