"blood supply: supraorbital, anterior and posterior ethmoidal and sphenopalatine arteries"
"They are separated into anterior and posterior groups by the basal lamella, the lateral attachment of the middle turbinate to the lamina papyracea. Historically the ethmoid sinuses were subdivided into 3 groups of air cells: the anterior, middle and posterior ethmoidal air cells. The middle group are now incorporated into the anterior group."
"From the ophthalmic branch of the internal carotid artery, the supraorbital, anterior and posterior ethmoidal arteries supply the ethmoid air cells with the sphenopalatine artery (a branch of the maxillary artery) also contributing. Thus, the ethmoid air cells are supplied by branches of both the internal and external carotid arteries."
