Detailed explanation-1: -The ethmoid bone is a small bone with a cuboidal structure that forms the lateral boundaries of the orbit, the anterior cranial fossa superiorly, and the nasal cavities inferiorly. [1] It is relatively light and has a spongy texture.
Detailed explanation-2: -Structure. The ethmoid bone is an anterior cranial bone located between the eyes. It contributes to the medial wall of the orbit, the nasal cavity, and the nasal septum.
Detailed explanation-3: -Here’s the bony part of the nasal septum. It’s formed by this part of the ethmoid bone, the perpendicular plate, and by this small bone that we haven’t encountered up till now, the vomer. The lowest part of the septum is formed by the maxilla and by the palatine bone. Here’s the divided left cribriform plate.
