The anterior ethmoidal artery, also anterior ethmoid artery is an artery of the head.

Contents

Course

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.
