The posterior ethmoidal artery is an artery of the head which arises from the ophthalmic artery to supply the posterior ethmoidal air cells, and the meninges.^[1] It is smaller than the anterior ethmoidal artery.^[2]

Anatomy

The posterior ethmoidal artery is an orbital branch of the ophthalmic artery.^[1]

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]

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]

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]}
