After passing through the carotid canal, the internal carotid artery appears inside the skull near the caudal border of the pituitary gland, and having given off the posterior communicating artery, runs forwards to the level of the optic chiasma. 2. This review deals with the various terminologies for the cerebral gyri and sulci on the superolateral, inferomedial, and basal surfaces of the cerebrum, aiming for a common terminology. The hippocampal formation, on the medial side of the lobe, includes the parahippocampal gyrus, subiculum, hippocampus, dentate gyrus, and associated white matter, notably the fimbria, whose fibres . inferomedial border inferolateral border Although the cerebral cortex has surfaces, they are not smooth owing to their embryonic development. Is formed by popliteal surface of femur, capsule of knee joint and fascia over . the popliteal vein lies between popliteal artery and tibial nerve. The Arteries of the Brain. Internal capsule is continuous superolaterally with pes coro nae radiatae (5) leading to stellate radiations into cerebral white matter.

Inferomedial - Separates the superolateral and inferior surfaces . The border between the corona radiata and sagittal stratum is positioned at a line (broken line) connecting the upper end of the parieto-occipital sulcus and the midpoint of the anterior edge of the limen insulae. PCA strokes can restrict the blood supply of multiple brain regions, including the occipital lobe, the inferomedial temporal lobe, a large portion of the . They show a series of grooves or sulci which are separated by intervening areas that are called gyri. 12.3 Inferior aspect of cerebral hemisphere showing borders, surfaces, and poles. Each cerebral hemisphere presents six borders (Figs 12.2 and 12.3), viz. 7 ). ascends toward the posteromedial border of the carotid sulcus, then curves anteriorly along the carotid sulcus, and again courses upward to emerge from the cavernous sinus inferomedial to the anterior clinoid process. Cerebrum •Constitute the greatest bulk part of the brain. The inferior gyri continues onto the inferior surface of the cerebral hemispheres. It has the following features: three surfaces: anterior (petrosal), superior (tentorial), inferior (suboccipital. Medical Definition of Inferomedial margin. The inferomedial border is divided into an anterior part called the medial orbital border and a posterior part called the medial occipital border This communicating pathway allows equalization of blood-flow between the two sides of the brain, and permits anastomotic circulation, should a part of the circulation be occluded. The medial occipital border separates the medial surface from the tentorial surface. The sagittal stratum is composed of occipitothalamic fibers, also called the optic radiations, and temporo- and occipitopontine fibers. .
