The ethmoid bone shapes the floor of the skull as well as its inferior lateral walls.
Where is an ethmoid bone found?
The upper nasal cavity's roof and lateral walls, the top part of the nostril septum, and a piece of the orbit's medial wall are all formed by the ethmoid bone, a single midline bone. The ethmoid also contributes to the anterior cranial cavity's floor on the inside of the skull.
The anterior cranial fossa's floor is formed by the ethmoid bone, which occupies a tiny space in the cranial cavity near the midline. This area also serves as the nasal cavity's slender roof. The cribriform plates and crista galli make up this section of the ethmoid bone.
