Glands responsible for secreting tears are A. Meibomian gland B. Glands of Moll C. Glands of Zeis D. Lacrimal glands
Hint: Tears play a variety of main functions in your body. They keep your eyes lubricated and help you wash away foreign particles and dust. They are also a part of your immune system that protects you from infection.
Complete Answer: - Glands under the skin of your upper eyelids create tears that contain water and salt. When you blink, tears fly, leaving your eyes moist. Other glands contain oils that prevent tears from evaporating too quickly or from leaking out of your eyes. - Tears are usually discharged into the tear ducts and then evaporated. When you make so many tears, they overpower your tear ducts, and you grow watery eyes. - Tear ducts and glands, also known as lachrymal or lacrimal, ducts and glands, which produce and distribute the watery portion of the tear film. - Tears are a dynamic, typically transparent fluid that is diffused between the eye and the eyelid. Other components of the tear film include the inner mucous layer formed by specialised conjunctival cells and the outer lipid layer formed by the meibomian glands along the eyelid margin. - Tears are continuously secreted from satellite (or accessory) lacrimal glands located high in the upper upper lid at a relatively regular rate. Reflex tears, such as those triggered by eye pain, bright lights, or emotional discomfort, are caused by the main lacrimal glands. - Each major lacrimal gland is situated in a hollow space in the inner surfaces of the front bone, positioned above and laterally in the eye. - Moll's gland, also known as Moll's gland or ciliary gland, is a modified apocrine sweat gland located at the edge of the eyelid. Moll's glands are empty into the adjacent lashes. Glands of Moll and Zeis secrete sebum, which keeps the lashes supple.
Thus the correct answer is option(D) Lacrimal Gland.
Note: Diseases that damage the lacrimal gland, and thereby reduce the secretion of tears, can lead to chronic dry eyes, which can eventually endanger vision. Treatment of persistent dry eyes consists of artificial lubrication and, in some cases, mechanical closure of the puncta or surgery to partially close the lids.
