The ethmoturbinals are associated with the cribiform plate. They are covered with olfactory epithelium. Primarily, they serve to increase the surface area over which olfactory receptor neurons can come in contact with respiratory air. These olfactory receptor nerves then synapse with the mitral cells of the olfactory lobes through the cribiform plate in the manner described above[Palaeos].
