Question

In a mammal, the eyes are lubricated by the secretion of

• A. Harderian glands
• B. Nictitating membrane
• C. Meibomian glands
• D. Lacrimal glands

Answer 1

Answer: (C)

Meibomian glands

Meibomian glands are tiny oil glands that are situated in the margin of the eyelids. These glands secrete oil that coats the surface of our eyes and keeps the water component of our tears from evaporating (drying out). Together, the water and the oil layer make up the tear film. This tear film lubricates and keeps the surface of our eyes healthy. It also affects how clearly we see.

So the correct option is C.
