Anatomy[edit]
The posterior ethmoidal artery is an orbital branch of the ophthalmic artery.[1]
Course and relations[edit]
After branching from the ophthalmic artery, the posterior ethmoidal artery passes between the upper border of the medial rectus muscle and superior oblique muscle[citation needed] to reach, enter and traverse the posterior ethmoidal canal.[3]
Branches[edit]
Meningeal branch
It emits a meningeal branch to the dura mater after entering the cranium.[2][3]
Nasal branches
It emits nasal branches that pass through the cribriform plate to reach the nasal cavity. The nasal branches form anastomoses with the sphenopalatine artery.[4]
Distribution[edit]
This artery supplies the posterior ethmoidal air sinuses, the dura mater[2] of the anterior cranial fossa, and the upper part of the nasal mucosa of the nasal septum.[citation needed]
