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 the inferior wall and is formed by three bones working together: the maxilla forms the majority of the floor, the zygomatic bone contributes to the lateral portion, and the palatine bone provides a portion of the posterior floor. This combination creates the complete orbital floor that separates the contents of the orbit from the maxillary sinus below. That’s why the three bones are the maxilla, palatine, and zygomatic. The other groupings are not correct because they either belong to the nasal cavity (not the orbit) or form other walls of the orbit (roof or medial wall) rather than the floor as a triad.
