The posterior meningeal artery is one of the meningeal branches of the ascending pharyngeal artery (and is typically considered the terminal branch of said artery). It passes through the jugular foramen to enter the posterior cranial fossa. [1] It is the largest vessel supplying the dura of the posterior cranial fossa. [citation needed]
The meningeal branches of vertebral artery (posterior meningeal branch) springs from the vertebral opposite the foramen magnum, ramifies between the bone and dura mater in the cerebellar fossa, and supplies the falx cerebelli. [1] [2] [3] It is frequently represented by one or two small branches.
The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin.
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals.

The falx cerebri receives its blood supply primarily from two vessels; the anterior portion receives blood supply from the anterior meningeal artery (a.k.a. anterior falx artery, or anterior falcine artery) (a branch of the anterior ethmoidal artery), and the posterior portion from the posterior meningeal artery (a branch of the ascending ...
It divides into two branches - anterior and posterior - which accompany the main divisions of the middle meningeal artery and supply the dura mater: [1] The anterior branch communicates with the meningeal branch of the maxillary nerve. [1] The posterior branch also supplies the mucous lining of the mastoid cells. [1]
The anterior ethmoidal artery is a branch of the ophthalmic artery in the orbit. [1] It exits the orbit through the anterior ethmoidal foramen alongside the anterior ethmoidal nerve. It contributes blood supply to the ethmoid sinuses, frontal sinuses, the dura mater, lateral nasal wall, and nasal septum. It issues a meningeal branch, and nasal ...
