NBEO Ocular Physiology Practice Exam

The accessory lacrimal glands that are found within the fornices are the Glands of Krause. These glands are situated in the conjunctival fornices and play a crucial role in tear production, contributing to the overall moisture and lubrication of the ocular surface.

The Glands of Krause are also considered important in the secretion of the aqueous component of tears, thus helping maintain a stable tear film. Their location allows them to effectively discharge their secretions into the conjunctival sac, assisting with the distribution of tears across the eye during blinking.

To further understand, other glands mentioned do not have this specific location or function. The Glands of Zeiss are sebaceous glands located at the base of the eyelashes, contributing to the lipid layer of the tear film but not found in the fornices. The Glands of Moll are modified sweat glands located near the eyelashes as well, while the Glands of Wolfring are found along the upper and lower eyelids but not specifically within the fornices. This distinction clarifies why the Glands of Krause are the correct answer in this context.
