Lacrimal gland
Lacrimal Gland
The Lacrimal Gland (pronounced: /ˈlækrɪməl/), is a small, almond-shaped structure that plays a crucial role in the production of tears. The term "lacrimal" is derived from the Latin word "lacrima," which means tear.
Anatomy
The Lacrimal gland is located in the upper outer portion of each eye socket (orbit), just inside the bony ridge of the eyebrow. It is divided into two parts: the larger orbital part and the smaller palpebral part. The gland produces the watery component of tears, which are essential for maintaining the health of the cornea and for providing a clear and smooth optical surface.
Function
The primary function of the Lacrimal gland is to produce and secrete tears. These tears are spread across the surface of the eye when we blink, providing moisture and nutrients to the cornea and conjunctiva. They also help to flush away any foreign bodies or irritants that may come into contact with the eye.
Related Terms
- Tears: The fluid produced by the lacrimal gland.
- Cornea: The clear front surface of the eye, which receives nutrients from the tears.
- Conjunctiva: The thin, transparent tissue that covers the front of the eye and the inner surfaces of the eyelids.
- Eye socket (Orbit): The bony cavity in the skull that contains the eye and its associated structures, including the lacrimal gland.
Disorders
Disorders of the Lacrimal gland can lead to dryness and irritation of the eyes, a condition known as Dry eye syndrome. This can result from insufficient tear production, which may be due to aging, certain medical conditions, or damage to the lacrimal gland.
