LACRIMAL APPARATUS Meaning and
Definition
-
The lacrimal apparatus is a vital structure in the human body responsible for producing and draining tears. It consists of various components working in synergy to maintain tear production and distribution for ocular lubrication and protection. The lacrimal apparatus primarily includes the lacrimal glands, lacrimal puncta, lacrimal canaliculi, lacrimal sac, and the nasolacrimal duct.
The lacrimal glands are responsible for the secretion of tears, which contain water, enzymes, mucus, antibodies, and electrolytes. Located above the outer corner of each eye, these glands release tears onto the ocular surface through tiny ducts.
The lacrimal puncta are small openings found at the inner corner of each eyelid. They act as entry points for tears onto the ocular surface. From there, tears are drained into the lacrimal canaliculi, which are thin channels that connect the puncta to the lacrimal sac. The lacrimal sac, located in a bony groove between the nose and eye socket, collects the tears and serves as a temporary reservoir. Finally, tears are drained from the lacrimal sac into the nasolacrimal duct, which connects the sac to the nasal cavity, allowing tears to be ultimately eliminated through the nostrils.
In summary, the lacrimal apparatus functions as a crucial system involved in tear production, distribution, and drainage, helping to maintain clear vision, eye health, and protection from harmful particles.
