The end part of the corpus callosum, towards the cerebellum, is called the splenium. This is the thickest part, and overlaps the tela choroidea of the third ventricle and the midbrain, and ends in a thick, convex, free border. Splenium translates as "bandage" in Greek. The trunk of the corpus callosum lies between the splenium and the genu.
The cave of septum pellucidum is bounded anteriorly by the genu of the corpus callosum, superiorly by the body of the corpus callosum, posteriorly by the anterior limb and pillars of the fornix, inferiorly by the anterior commissure and the rostrum of the corpus callosum, and laterally by the leaflets of the septum pellucidum.

The cingulate gyrus commences below the rostrum of the corpus callosum, curves around in front of the genu, extends along the upper surface of the body, and finally turns downward behind the splenium, where it is connected by a narrow isthmus with the parahippocampal gyrus.
The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain.
The subcallosal gyrus (paraterminal gyrus, peduncle of the corpus callosum) is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum with the indusium griseum.
The indusium griseum is prolonged around the splenium of the corpus callosum as a delicate layer, the fasciolar gyrus, [3] which is continuous below with the surface of the dentate gyrus. [4] The indusium griseum and fasciolar gyrus are very small components of the limbic lobe , and are continuations of the hippocampal formation, forming an ...
Agenesis of the corpus callosum (ACC) is a rare birth defect in which there is a complete or partial absence of the corpus callosum.It occurs when the development of the corpus callosum, the band of white matter connecting the two hemispheres in the brain, in the embryo is disrupted.
The impact of the SFO on the cardiovascular system is mostly mediated through its influence on fluid balance. [1] The SFO plays a role in vasopressin regulation. Vasopressin is a hormone that, when bound to receptors in the kidneys, increases water retention by decreasing the amount of fluid transferred from blood to urine by the kidneys.
