Which bones are small and thin, located at the inner wall of the orbits?

Lacrimal bones are indeed the correct answer because they are small and thin bones located in the medial wall of the orbit, which is the bony cavity that contains the eye. Each lacrimal bone contributes to the inner structure of the eye socket and plays an essential role in forming the tear duct system. Their positioning allows for the passage of tears from the lacrimal sac to the nasal cavity, facilitating proper tear drainage.

In contrast, the maxillae, zygomatic bones, and nasal bones have different characteristics and functions. The maxillae are larger, forming the upper jaw and part of the orbit but are not classified as small and thin. Zygomatic bones, also known as the cheekbones, provide structure to the face and are much more prominent. Nasal bones, while small, are located at the bridge of the nose and do not form part of the orbital wall. This anatomical knowledge helps clarify the distinctive role and location of the lacrimal bones in the facial skeleton.
