lacrimal gland, lachrymal gland, tear gland(noun)
any of the glands in the eyes that secrete tears
One of a pair almond-shaped glands, one for each eye, that secrete the aqueous layer of the tear film.
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 lacriminal gland produces tears which then flow into canals that lead to the lacriminal sac. From this sac, the tears drain through a passage into the nose. Anatomists divide the gland into two sections. The smaller palpebral portion, lies close to the eye, along the inner surface of the eyelid; if the upper eyelid is everted, the palpebral portion can be seen. The orbital portion contains fine interlobular ducts that unite to form 3 - 5 main excretory ducts, joining 5 - 7 ducts in the palpebral portion before the secreted fluid may enter on the surface of the eye. Tears secreted collect in the fornix conjunctiva of the upper lid, and pass over the eye surface to the lacrimal puncta, small holes found at the inner corner of the eyelids. These pass the tears on to the lacrimal sac, in turn to the nasolacrimal duct, which dumps them out into the nose.
