The perpendicular plate of the ethmoid bone (vertical plate) is a thin flattened lamina polygonal in form which descends from the under surface of the cribriform plate and assists in forming the septum of the nose; it is generally deflected a little to one or other side. The anterior border articulates with the spine of the frontal bone and the crest of the nasal bones. The posterior border articulates by its upper half with the sphenoidal crest by its lower with the vomer.
