Maxillary Artery. View from inside. 



The branches of the second or pterygoid portion of 

 the internal maxillary artery are the following : 



a) The masseteric, Ramus masseterkus, for the M. masseter, which 

 passes through the sigmoid notch of the lower jaw ; 



b) The buccal, Eamus buccinatorius, for the M. buccinator, whose 

 twigs anastomose with those of the infraorbital, transverse facial and 

 facial arteries; 



c) The pterygoid, Eami pterygoidci, for both MM. pterygoidei; 



d) The deep temporal, Art. temporales profundae, which are two 

 in number, an anterior and a posterior, for the temporal muscle. 

 The anterior Art. temporalis profunda, sends a branch through the 

 Canalis zygomaticus temporalis into the orbit, where it anastomoses with 

 the lachrymal artery (see Fig. 543).
