Maxillary nerve

This tutorial covers the anatomy and function of the maxillary nerve, a branch of the trigeminal nerve. It details the nerve's course, its branches, and their respective innervations. The tutorial also discusses the trigeminal ganglion and the pterygopalatine fossa. Clinical correlations such as maxillary nerve block and orbital blowout fractures are explored, highlighting their implications on sensation in the upper jaw and face.
