What is the light spongy bone located between the eye sockets that also forms part of the nasal cavities?

The light spongy bone located between the eye sockets that also forms part of the nasal cavities is the ethmoid bone. This bone plays a crucial role in the structure of the skull as it is situated in the midline of the skull, helping to form the bony structure of the nasal cavity and the orbit of the eyes. Its spongy nature allows it to be lightweight yet strong, which is essential for providing support while also contributing to the overall shape of the face.

The ethmoid bone contains numerous small openings that allow for the passage of olfactory nerves, which are responsible for the sense of smell. Its location and structure make it an integral component of both the nasal and orbital cavities, connecting these two essential areas of the skull.
