The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, as well as the medial and inferior aspects of the temporal lobe of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral ...
Each posterior communicating artery is situated within the interpeduncular cistern, superolateral to the pituitary gland. [2]: 450 Each are is situated upon the medial surface of the ipsilateral cerebral peduncle [1]: 477 and adjacent to the anterior perforated substance.
The posterior cerebral circulation is the blood supply to the posterior portion of the brain, including the occipital lobes, cerebellum and brainstem. It is supplied by the following arteries: It is supplied by the following arteries:
The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]
The posterior communicating artery is given off as a branch of the internal carotid artery just before it divides into its terminal branches - the anterior and middle cerebral arteries. The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle.
The internal carotid artery; The origin of the anterior choroidal artery; The origin of the posterior communicating artery; Cistern of lateral cerebral fossa. It is situated in the fissure between the frontal and temporal lobes. It contains: The middle cerebral artery; The middle cerebral veins; The fronto-orbital veins; Collaterals to the ...
The artery of Percheron (AOP) is a rare anatomical variation in the brain vascularization in which a single arterial trunk arises from the posterior cerebral artery (PCA) to supply both sides of the thalamus and midbrain.
The anatomy of external carotid artery is access via AP and lateral views. [8] To image the posterior circulation, such as vertebral and basilar arteries, AP, Towne's view, lateral projections near the back of the head and upper part of the neck is taken.
