=====Anterior ethmoidal artery=====
The anterior [[ethmoidal artery]], also anterior ethmoid artery.

Once it branches from the [[ophthalmic artery]], it accompanies the [[nasociliary nerve]] through the anterior ethmoidal canal to supply the anterior and middle ethmoidal cells, [[frontal sinus]], and anterosuperior aspect of the lateral nasal wall.

====Branches====
When entering the cranium, it gives off:

A meningeal branch to the dura mater.

Nasal branches. These descend into the nasal cavity through the slit by the side of the [[crista galli]], and, running along the groove on the inner surface of the nasal bone, supply branches to the lateral wall and septum of the nose, and a terminal branch which appears on the dorsum of the nose between the nasal bone and the lateral cartilage.
