Verified step by step guidance

Step 1: Begin by identifying the anatomical location of the lacrimal groove. The lacrimal groove is a depression found in the frontal process of the maxilla, near the medial wall of the orbit.

Step 2: Understand the function of the lacrimal groove. It serves as a pathway for structures involved in tear drainage, specifically the nasolacrimal duct.

Step 3: Review the role of the nasolacrimal duct. This duct connects the lacrimal sac to the nasal cavity, allowing tears to drain from the eyes into the nasal cavity.

Step 4: Eliminate the incorrect options based on their anatomical locations and functions: The optic nerve is located in the posterior orbit, the maxillary sinus is a hollow cavity within the maxilla, and the mandibular foramen is located on the mandible.

Step 5: Conclude that the structure located within the lacrimal groove is the nasolacrimal duct, as it matches both the anatomical location and function described.
