Osteology
Roentgenogram, ethmoid bone, anteroposterior view
The ethmoidal labyrinths (6) consist of numerous air cells separated by thin bony walls, and are connected at their superior margins by the cribriform plate (2). The superior surface of the cribriform plate lies in the anterior cranial fossa while its inferior surface forms the roof of the nasal fossae.
