Artery Meningeal Posterior Internal

The Meningeal Posterior Internal Artery is one of the arteries that supplies the brain with blood. It is located inside the skull, between the dura mater and the arachnoid mater. The posterior internal meningeal artery originates from the internal carotid artery, passes through the middle cranial fossa and enters the cranial cavity through the foramen magnum.

The posterior internal meningeal artery is a branch of the internal carotid artery and runs inside the skull parallel to other arteries. It provides blood supply to the meninges and also participates in the formation of venous outflow from the brain.

One of the functions of the arterial system of the brain is to provide the brain with oxygen and nutrients. The posterior internal meningeal arteries are involved in this process, providing blood supply to the meninges and brain tissue. In addition, they are involved in the metabolism of glucose, fats and other substances necessary for normal brain function.

The posterior internal meningeal artery (c. meningica posterior interna; syn.: a. meningealis posterior interna, c. meningo-spinalis posterior interna) is an artery that is a branch of the internal carotid artery. The lateral part of this artery passes through the foramen magnum of the occipital bone and becomes the Z. m.a. Along the medial wall of the midbrain sulcus, it reaches the large foramen of the cerebellar vermis and there it divides into anterior and posterior branches, which connect this artery with the posterior inferior
