 connected in this situation with the auriculo-temporal branch of the inferior 

 maxillary nerve, and divides into branches which are distributed over the temple 

 and upper part of the face ; these are divided into three sets temporal, malar, and 

 infra-orbital.

The temporal branches cross the zygoma to the temporal region, supplying the 

 Attrahens and Attollens aurem muscles, and join with the temporal branch of the 

 temporo-malar, a branch of the superior maxillary, and with the auriculo-tem- 

 poral branch of the inferior maxillary. The more anterior branches supply the 

 frontal portion of the Occipito-frontalis, the Orbicularis palpebrarum, and Corruga- 

 tor supercilii muscles, joining with the supra-orbital and lachrymal branches of 

 the ophthalmic. 



The malar branches pass across the malar bone to the outer angle of the orbit, 

 where they supply the Orbicularis palpebrarum muscle, joining with filaments from 

 the lachrymal nerve; others supply the lower eyelid, joining with filaments of the 

 malar branch (subcutaneus malce) of the superior maxillary nerve. 



The infra-orbital, of larger size than the rest, pass horizontally forward to be 

 distributed between the lower margin of the orbit and the mouth. The superficial 

 branches run beneath the skin and above the superficial muscles of the face, which 

 they supply : some branches are distributed to the Pyramidalis nasi, joining at the
