The anterior ethmoidal artery, also anterior ethmoid artery is an artery of the head.
Contents |
Course
It accompanies the nasociliary nerve through the anterior ethmoidal canal, supplies the anterior and middle ethmoidal cells and frontal sinus, and enters the cranium
Branches
When entering the cranium, it gives off:
- a meningeal branch to the dura mater, also known as the "anterior meningeal artery".
- 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 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.
