All of these are branches of maxillary nerve in pterygopalatine fossa except: 
Select and explain. 
A. Zygomatic nerve, B. Infraorbital nerve, C. Pterygopalatine nerve, D. Posterior superior alveolar nerve
B: Infraorbital nerve
Answer: B: Infraorbital nerve 
Explanation: Infraorbital nerve emerges within the orbit.
Gives 2 branches:
Middle superior alveolar nerve - arises in infraorbital groove.  
Anterior superior alveolar nerve - arises in infraorbital canal.
Branches of maxillary nerve in pterygopalatine fossa:

Zygomatic nerve:-
	
Zygomaticotemporal
Zygomaticofacial


Ganglionic branches (branches of pterygopalatine ganglion). 
 Posterior superior alveolar nerve


KEY CONCEPT:
Infraorbital nerve is the continuation of maxillary nerve. Enters the orbit through inferior orbital ﬁssure.
