A spongy bone located between both eye sockets is which bone?

• A. Nasal
• B. Ethmoid
• C. Parietal
• D. Occipital

Answer: (B)

Between the eye sockets sits a light, spongy bone called the ethmoid. Its interior is cancellous—packed with small air cells in the ethmoidal labyrinth—giving it a porous, sponge-like texture. The ethmoid forms part of the medial walls of the orbits and contributes to the nasal cavity and nasal septum. The other bones described don’t lie between the orbits: the nasal bone is in front of the nose, the parietal bones are on the sides/top of the skull, and the occipital bone is at the back. So the spongy bone between the eye sockets is the ethmoid.
