Which are the smallest two bones of the facial skeleton forming part of the inner, bottom wall of the eye socket?

• A. Lacrimal
• B. Nasal
• C. Zygomatic
• D. Ethmoid

Answer: (A)

Two tiny bones sit at the inner corner of each eye socket, and they’re the smallest bones in the facial skeleton. These lacrimal bones form part of the medial (inner) wall of the orbit and sit near the nasal cavity, helping define that inner boundary of the eye socket. The other options don’t fit this description: nasal bones form the nose bridge, zygomatic bones make up the cheek and the lateral orbit, and the ethmoid, while it does contribute to the medial wall, is considered a cranial bone—not one of the smallest facial bones.
