Which glands are responsible for keeping the conjunctiva moist?

Pituitary glands
Thyroid glands
Lacrimal glands
Adrenal glands

The correct answer is: Lacrimal glands

The lacrimal glands are specialized structures located in the upper outer region of each orbit, just above the eyeball. Their primary function is to produce tears, which play a crucial role in maintaining the moisture of the conjunctiva, the thin membrane covering the front of the eye and the inner surfaces of the eyelids. Tears help in lubrication, providing protection against foreign particles, and maintaining a smooth optical surface that is essential for clear vision. In contrast, the pituitary glands are involved in hormone regulation throughout the body but do not have a direct role in producing tears or keeping the conjunctiva moist. The thyroid glands primarily regulate metabolism and energy management rather than eye moisture. The adrenal glands produce hormones related to stress response and metabolism, but they also do not contribute to ocular lubrication. Therefore, the lacrimal glands are uniquely suited to this function, making them the correct answer to the question.
