oculi and to the frontal belly of the epicranius. One of the 

 branches communicates with the zygomatico-temporal branch 

 of the trigeminal nerve, which pierces the temporal fascia 

 behind the zygomatic bone. 



The upper filaments of the zygomatic branches run forwards 

 across the zygomatic bone, and terminate, in both the upper 

 and the lower eyelid, in the fibres of the orbicularis oculi. 

 If the branches are carefully traced, one of them will be 

 found to communicate with the zygomatico-facial branch 

 of the second or maxillary division of the trigeminal nerve.
