Final answer:
The ethmoid bone is the bone that forms part of the interior of the nasal cavity and contributes to the medial wall of the orbit for the eye.
Step-by-step explanation:
The bone that forms part of the interior of the nasal cavity and the orbit for the eye is the ethmoid bone. The ethmoid bone plays a significant role in the structure of the nasal cavity and the orbit. It is responsible for forming the roof and lateral walls of the upper nasal cavity, the upper portion of the nasal septum, and contributes to the medial wall of the orbit.
The anterior skull consists of several bones that together form the eye orbits and the nasal structure. The nasal septum is primarily built by the perpendicular plate of the ethmoid bone, along with the vomer bone and the septal cartilage. For the orbit, the ethmoid contributes to its medial wall along with six other bones that collectively create the structure housing the eyes.
