Belonging to the ethmoid bone; as, Ethmoidal cells, E. suture, &c. The Ethmoidal apophysis or process is the advanced part of the sphenoid bone, which articulates with the ethmoid. The ethmoidal arteries are two in number, the anterior of which arises from the ophthalmic artery. The origin of the other varies. The Ichancrure ethmoidale of the os frontis receives the ethmoid bones. The Ethmoidal veins correspond to the arteries.
