Medial View of Right Hemisphere

Surgical Correlation

Tags

Medial view of right hemisphere. The corpus callosum is seen cut in sagittal view and its surface is followed by branches of the anterior cerebral artery supplying most of the medial surface of the cerebrum. The right caudate nucleus is visible below the cerebral cortex and next to the lateral ventricle. The choroid plexus of the lateral and third ventricles is outlined. The midline pineal gland projects posteriorly into the quadrigeminal cistern and is located just rostral to the superior colliculus. The medial posterior choroidal artery wraps around the midbrain to supply the thalamus, choroid plexus of the third ventricle, and tectum of the midbrain. The falx cerebri is a dural fold that separates the two hemispheres. It attaches in the midline to the superior surface of the tentorium cerebelli. A window has been cut out to expose the superior surface of the cerebellum. The anterior edge of the tentorium forms a notch (tentorial notch or incisura) around the midbrain.  Branches of the posterior cerebral artery (terminal branch of the basilar artery) course above the tentorium toward the occipital lobe, while branches of the superior cerebellar artery pass below it to the superior surface of the cerebellum. The posterior attachment of the tentorium to the occipital bone contains the transverse sinus. The left middle cerebral artery has been cut where it enters the Sylvian fissure. The left temporal lobe has been removed from the floor of the middle cranial fossa. (Image courtesy of PA Rubino)
