Anterior lateral nasal branches of anterior ethmoidal artery

The anterior ethmoidal artery is a branch of the ophtlamic artery. It accompanies the nasociliary nerve through the anterior ethmoidal canal, supplies the anterior and middle ethmoidal cells and frontal sinus, and, entering the cranium, gives off a meningeal branch (Anterior meningeal branch) to the dura mater, and nasal branches; these latter 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 (Anterior lateral nasal branches) and septum (Anterior septal branches) of the nose, and a terminal branch which appears on the dorsum of the nose between the nasal bone and the lateral cartilage.
