Where in the body are tear (lacrimal) glands located? Lacrimal glands are located next to the outer side of the eye within the eye socket (orbit). More specifically they are located in the supero-lateral region of the orbit within the lacrimal fossa of the frontal bone. They are responsible for producing the aqueous component of tears. Whereas the lacrimal gland produces tears, they are stored in lacrimal sacs located to the inner side of the eye within the orbit.

- The pineal is a small, cone shaped gland attached to the posterior ceiling of the third ventricle of the brain, suspended in cerebrospinal fluid. Its location in the center of the brain, combined with its unique proclivity to calcify, make it a valuable landmark for neuroradiologists.

- Transport of IgA. Another major function of the lacrimal gland acinar cells is to move dimeric IgA from the interstitial fluid into the tear ducts and thus onto the ocular surface. IgA is produced by plasma cells resident in the lacrimal gland.he nature of tear fluid. The fluid secreted by the lacrimal glands is a complex solution of ions and proteins produced by two resident secretory cell populations: the plasma cells of the immune system and the acinar and duct cells of the secretory epithelium of the gland.

- Lacrimal gland lies in the anterior lateral portion of the orbit in the lacrimal fossa. Large orbital portion (3 - 5 ducts) and smaller palpebral portion (5 - 7 ducts) See 01 and 02 Anatomy notes for blood supply and innervation.

Lacrimal gland The lacrimal glands are paired almond-shaped glands, one for each eye, that secrete the aqueous layer of the tear film. They are situated in the upper, outer portion of each orbit, in the lacrimal fossa of the orbit formed by the frontal bone.Inflammation of the lacrimal glands is called dacryoadenitis.The lacrimal gland produces tears which then flow into canals that lead to the lacrimal sac. From this sac, the tears drain through the lacrimal duct into the nose. Anatomists divide the gland into two sections.nflammation of the lacrimal glands is called dacryoadenitis.

- Excess tears are drained from the medial aspect of the conjunctival sac via the canaliculi into the lacrimal sac and nasolacrimal duct, to empty into the inferior meatus of the nasal cavity (Fig. 1-63).

- Tears are produced in the lacrimal gland and drain through the upper and lower puncta into the canaliculi and then into the lacrimal sac and nasolacrimal duct (see Figure: Anatomy of the lacrimal system. ). Obstruction of tear drainage can lead to stasis and infection.

Anatomy of the Eye The lacrimal gland produces tears that lubricate the eye. It is located under the lateral edge of the eyebrow in the orbit. Tenon’s Capsule: Tenon’s capsule is a layer of tissue that lies between the conjunctiva and the surface of the eye. Sclera: The sclera is the white outer wall of the eye. It covers nearly the entire surface of the eyeball.

Overview Dacryocystitis is an infection of the tear sac (lacrimal sac) in the inner corner of your eye. Tears drain through this sac as they leave your eyes. Tears help keep your eyes hydrated, clean, and free of bacteria. The lacrimal glands underneath your upper eyelids produce tears, which travel through small openings to the front of your eye. Every time you blink, the tears spread across your eyes.

Lacrimal gland - Glandula lacrimalis The ducts of the glands, from six to twelve in number, run obliquely beneath the conjunctiva for a short distance, and open along the upper and lateral half of the superior conjunctival fornix. In structure and general appearance the lacrimal resembles the serous salivary glands. In the recent state the cells are so crowded with granules that their limits can hardly be defined. They contain oval nuclei, and the cell protoplasm is finely fibrillated.

Tear Duct Surgery Tears normally drain into small holes located in the inside corner of the upper and lower eyelids. The tears then collect in the tear sac. The tear sac lies under the skin between the corner of the eye and the nose. Next, the tears flow through a small tube, called the nasolacrimal duct, into the nose.ears normally drain into small holes located in the inside corner of the upper and lower eyelids.
