What structure is found in the lacrimal fossa?

The lacrimal fossa is a depression located in the frontal bone of the skull, specifically at the medial aspect of the orbit. It houses the lacrimal sac, which is part of the tear drainage system. The lacrimal sac collects tears from the eye and channels them into the nasolacrimal duct, leading to the nasal cavity. This structure is essential for maintaining proper tear flow and drainage.
