The preganglionic parasympathetic axons synapse in the pterygopalatine ganglion, which contains the postganglionic neurons which provide secretomotor innervation to the lacrimal gland, as well as the nasal and palatine glands.

The nerve of the pterygoid canal forms from the junction of the greater petrosal nerve and the deep petrosal nerve within the foreamen lacerum. This combined nerve exits the foramen lacerum and travels to the

The postganglionic sympathetic axons do not synapse in the pterygopalatine ganglion, they travel on the branches of the maxillary nerve to provide sympathetic innervation to blood vessels.
