  7. Lacritin - Wikipedia

    en.wikipedia.org/wiki/Lacritin

    Most lacritin is produced by the lacrimal gland, [4] including the accessory lacrimal gland of Wolfring. [10] Some lacritin is produced by the meibomian gland, and by epithelial cells of the conjunctiva and cornea. [11] Together these epithelia comprise much of the lacrimal functional unit (LFU). Dry eye is the most common disease of the LFU.

    The lacrimal apparatus. Right side. Outline of bones of face, showing position of air sinuses. The nasolacrimal duct (also called the tear duct) carries tears from the lacrimal sac of the eye into the nasal cavity. [1][2] The duct begins in the eye socket between the maxillary and lacrimal bones, from where it passes downwards and backwards.
