posterior meningeal artery
The surgeon carefully identifies the posterior meningeal artery during the procedure.
Noun: A small artery that is a branch of the ascending pharyngeal artery. Its primary function is to supply oxygenated blood to the dura mater, the tough outer membrane covering the brain, specifically within the posterior cranial fossa. This is the deep, bowl-shaped area at the base of the skull that contains the cerebellum and brainstem.
The term is used in precise anatomical, medical, and surgical contexts to describe this specific blood vessel. - During the dissection, the surgeon carefully identified and preserved the posterior meningeal artery. - An aneurysm of the posterior meningeal artery is a rare but serious condition.
- Clinical Significance: Knowledge of the posterior meningeal artery's location is critical in neurosurgery and interventional radiology to avoid accidental injury during procedures involving the posterior skull base or to target it for embolization in cases of abnormal bleeding.
- Ascending pharyngeal artery: The parent artery from which the posterior meningeal artery branches.
- Dura mater: The membrane supplied by this artery.
- Posterior cranial fossa: The specific anatomical region where this artery is located.
- Meningeal arteries: The general class of arteries supplying the meninges (e.g., middle meningeal artery, anterior meningeal artery).
There are no direct common synonyms for this precise anatomical term. In general descriptive language, one might refer to it as a meningeal branch of the ascending pharyngeal artery.
- Arterial supply to the dura: A general phrase describing the function of vessels like the posterior meningeal artery.
- Posterior fossa vasculature: A broader term encompassing all arteries and veins in that region, including the posterior meningeal artery.

- branch of the ascending pharyngeal artery that supplies the dura mater of the posterior cranial fossa
