Which bone forms part of the nasal cavity between the eyes?

• A. Ethmoid
• B. Sphenoid
• C. Maxilla
• D. Zygomatic

Answer: (A)

The ethmoid bone is the one that forms part of the nasal cavity between the eyes. It sits between the two eye sockets and helps shape the nasal septum and the medial wall of the nasal cavity, including the perpendicular plate that contributes to the nasal septum. Its central location in the skull is what places it right in the area between the eyes. The sphenoid is located more posteriorly and forms part of the skull base and back of the nasal cavity; the maxilla makes up the upper jaw and much of the hard palate and lateral wall of the nasal cavity; the zygomatic forms the cheekbone and part of the orbital rim.
