The correct answer is option 1, "Eye." Meibomian glands are tiny oil-producing glands located along the rim of the eyelids. They are named after Heinrich Meibom, a German physician who first described them in the 17th century. These glands secrete a thick, oily substance called meibum that helps lubricate the surface of the eye and prevent the tears from evaporating too quickly. The meibum produced by the Meibomian glands also helps to maintain the stability of the tear film and prevent the tears from overflowing onto the cheeks. Dysfunction or blockage of the Meibomian glands can lead to a condition called Meibomian gland dysfunction (MGD), which is characterized by dry, irritated eyes and may contribute to the development of conditions like dry eye syndrome.
