The three bones that constitute the floor of the orbit are?

• A. Nasal, Vomer, Inferior Turbinate
• B. Maxillary, Palatine, Zygomatic
• C. Frontal, Ethmoid, Lacrimal
• D. Sphenoid, Zygomatic, Lacrimal

Answer: (B)

The floor of the orbit is a composite of three bones: the maxilla forms the main, anterior part; the zygomatic bone contributes laterally; and the palatine bone provides a small posterior portion. Together these three create the underside of the eye socket.

The nasal bones, vomer, and inferior turbinate belong to the nasal cavity and do not contribute to the orbital floor. The frontal, ethmoid, and lacrimal bones are more involved in the roof and medial wall, while the sphenoid participates toward the back of the orbit. So the combination that best matches the floor’s actual composition is the maxilla, zygomatic, and palatine bones.
