Anatomical terminology |
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]
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]
