1. Causes include idiopathic, congenital alacrima, xerophthalmia, lacrimal gland ablation, and sensory denervation. 2. Tears are produced by the lacrimal gland , situated just outside the eye. 3. The lacrimal gland is primarily responsible for producing emotional or reflexive tears. 4. Together, they function to collect tears produced by the lacrimal glands . 5. The lacrimal gland and the accessory conjunctival glands produce fewer tears. 6. However, they continue to course with the parasympathetic fibers innervating the lacrimal gland . 7. These fibers will eventually provide innervation to the lacrimal gland . 8. The apparatus includes the lacrimal gland and the accessory lacrimal gland, which produce the tears. 9. The apparatus includes the lacrimal gland and the accessory lacrimal gland , which produce the tears. 10. These parasympathetic to the lacrimal gland control tear production.
