The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [3] It consists of: The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the human eye; it is a serous gland located in lacrimal fossa. It is a j-shaped gland;
The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.

Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals. [1] Tears are made up of water, electrolytes, proteins, lipids, and mucins that form layers on the surface of eyes. [2] The different types of tears—basal, reflex, and emotional—vary significantly in composition. [2]

The lacrimal caruncle is found at the medial canthus of the eye. [1] It consists of skin, hair follicles, sebaceous glands, sweat glands, accessory lacrimal tissue and other tissues that are present in the skin and accessory lacrimal glands. [1] [2] Its non-keratinized epithelium resembles the conjunctival epithelium. [2]

Lacritin's discovery emerged from a screen for factors that stimulate tear protein secretion. Lacritin is a secreted ...
Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands (glandulae lacrimales accessoriae) found in the lacrimal caruncle of the eyelid. These accessory lacrimal glands are located in the upper border of the tarsus , approximately in the middle between the extremities of the tarsal glands . [ 1 ]
