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. 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.
The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [1] The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye; it is a j-shaped serous gland located in lacrimal fossa. The lacrimal canaliculi, the lacrimal sac ...
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;
Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions. Lactoferrin is also present in secondary granules ...
Accessory lacrimal glands. Krause's glands and Wolfring's glands (or Ciaccio's glands) are the accessory lacrimal glands of the lacrimal system of human eye. [1] These glands are structurally and histologically similar to the main lacrimal gland. Glands of Krause are located in the stroma of the conjunctival fornix, and the glands of Wolfring ...
Lactoperoxidase is a peroxidase enzyme secreted from mammary, salivary and other mucosal glands including the lungs, bronchii and nose [5] that functions as a natural and the first line of defense against bacteria and viruses. [6] Lactoperoxidase is a member of the heme peroxidase family of enzymes. In humans, lactoperoxidase is encoded by the ...
Lacritin is a 12.3 kDa glycoprotein encoded in humans by the LACRT gene. [3][4] Lacritin's discovery emerged from a screen for factors that stimulate tear protein secretion. [4][5] Lacritin is a secreted protein found in tears and saliva. Lacritin also promotes tear secretion, [4][6] the proliferation [4] and survival of epithelial cells, [7 ...
