Which of the following lists best describes the pathway of tears from the lacrimal glands to the nasal cavity?

Which of the following best describes the pathway of parasympathetic fibers to the lacrimal gland?
Parasympathetic fibers from CN VII travel first via the greater petrosal nerve and then via the nerve of the pterygoid canal to the pterygopalatine ganglion, where they synapse with postsynaptic fibers. These fibers join the zygomatic branch of V2, which in turn conveys the fibers to the lacrimal branch of V1 (via a communicating branch). This nerve delivers the parasympathetic fibers to the lacrimal gland

Which of the following muscles is NOT properly matched with it main action?
The superior oblique abducts, depresses, and rotates the eyeball medially
Which of the following nerves is correctly matched with its distribution?
The long ciliary nerves convey postsynaptic sympathetic fibers to the dilator pupillae and afferent fibers from the iris and cornea
