The anterior ethmoidal nerve is a branch of the nasociliary nerve. The anterior ethmoidal nerve goes along with the anterior ethmoidal artery and along with the frontal bone exits the orbit in the middle of the ethmoidal labyrinth via a canal.
- It then travels forward in an indentation on the cribriform plate and also goes in the nasal cavity by directly going laterally towards the crista galli and downwards via a foramen.
- It has branches towards the medial and lateral wall of the nasal cavity and afterwards proceeds forward on the undersurface of the nasal bone.
Before ending as the external nasal nerve, it travels over the external surface of the nose from going in the middle of the nasal bone as well as lateral nasal cartilage.
- Adjacent ethmoidal cells
- Frontal sinus
