thıs answer ıs not acceptable becouse we use pathway for nerve and thıs pathway start from nucleus ın braın through facıal nerve and greater petrosal nerve enter the pterıgoıd canal and then to enter pterıgopalatın ganglıa and post ganglıonıc fıber travel through maxıllary nerve and zygomatıc nerve zygomatıcotemporal then lacrımal nerve and then supply lacrımal gland .and for tear we use secretıon or draınge ınstead of pathway wıth best regard

Editor: Sami, I appreciate your input … however, I disagree with your terminology. I’ve never heard of the term “pathway” being reserved for the nervous system. Pathway can be used for other systems, especially those involving fluid movement (i.e. digestive pathway, aqueous pathway, tear pathway, lymphatic pathway) and chemical reactions (metabolic pathway, endocrine pathway).

Perhaps this terminology is strict where you trained, but pathway=nerve is not a universal convention.
