✅ The lacrimal glands are paired, almond-shaped exocrine glands responsible for producing the aqueous (watery) component of tears, which is essential for lubricating, nourishing, and protecting the surface of the eye.
✅ Located in the superolateral orbit of each eye within a depression of the frontal bone called the lacrimal fossa, these glands are key components of the lacrimal apparatus.
❄️Anatomy and Structure❄️
✔️The main lacrimal gland is about 2 cm in length and is partially divided into two lobes by the tendon of the levator palpebrae superioris muscle:
✔️Orbital Lobe (Superior): The larger, deeper portion situated in the lacrimal fossa.
✔️Palpebral Lobe (Inferior): The smaller portion located closer to the eye, along the inner surface of the upper eyelid, which can sometimes be seen when the lid is everted.
✳️Histology: The gland is composed of serous and mucinous acini (secreting cells) and myoepithelial cells, which contract to expel fluid.
✳️Ducts: Around 12 main excretory ducts from both lobes empty into the superior conjunctival fornix.
