Notes

The fossa for lacrimal gland (fossa glandulae lacrimalis) is a shallow depression located in the orbital plate of the frontal bone. This anatomical feature is specifically designed to accommodate the lacrimal gland, which is responsible for the production of tears.

Anatomy

The fossa for lacrimal gland is situated in the upper, outer part of the orbit, near the orbital margin. It is bordered by the orbital plate of the frontal bone and is adjacent to the supraorbital notch or supraorbital foramen. The fossa provides a protective space for the lacrimal gland, ensuring it is securely housed within the orbit.

Function

The primary function of the fossa for lacrimal gland is to house the lacrimal gland, which plays a crucial role in the lacrimal apparatus. The lacrimal gland produces tears that lubricate the eye, providing necessary moisture and protection against foreign particles and infections.

Clinical Significance

Any abnormalities or injuries to the fossa for lacrimal gland can affect the function of the lacrimal gland, potentially leading to conditions such as dry eye syndrome or dacryoadenitis. Surgical procedures involving the orbit must take care to avoid damage to this area to preserve the function of the lacrimal gland.
