Which bone is part of the facial skeleton and forms part of the orbit's medial wall?

• A. A Lacrimal
• B. B Mandible
• C. C Maxilla
• D. D Zygomatic

Answer: (A)

The medial wall of the orbit is formed by several facial bones, with the lacrimal bone sitting right at the front of that wall. It’s a small, delicate bone located at the inner corner of the orbit and contributes to the medial boundary, alongside contributions from the ethmoid and maxilla. This makes the lacrimal bone the best choice among the options for forming part of the medial wall. The mandible doesn’t touch the orbit, and while the maxilla does help build the medial wall, the lacrimal bone is the specific bone most closely associated with that wall. The zygomatic bone forms the lateral wall, not the medial one.
