De Lacoste-Utamsing and Holloway found that the shape of a portion of the corpus callosum called the splenium differed so dramatically between the sexes, with the splenium being larger in women than in men, that impartial observers were able to sex brains easily by looking at this single feature. ❋ Unknown (1997)
Its thick posterior end, termed the splenium, overlaps the mid-brain, but is separated from it by the tela chorioidea of the third ventricle and the pineal body. ❋ Unknown (1918)
The posterior end is termed the splenium and constitutes the thickest part of the corpus callosum. ❋ Unknown (1918)
Arching backward from immediately behind the anterior commissure to the under surface of the splenium is a second white band named the fornix: between this and the corpus callosum are the laminæ and cavity of the septum pellucidum. ❋ Unknown (1918)
Fausto-Sterling during an interview not long ago itemized some of the results from a long line of attempts to replicate sexual dimorphism: "1985: no sex differences in shape, width, or area. 1988: three independent observers unable to distinguish male from female. 1989: women had smaller callosal areas but larger percent of area in splenium, more-slender CCs, and more-bulbous splenium." ❋ Unknown (1997)
It 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 hippocampal gyrus. ❋ Unknown (1918)
Beginning in front at the anterior perforated substance, it passes forward and upward parallel with the rostrum, winds around the genu, runs backward above the corpus callosum, turns around the splenium, and ends in the hippocampal gyrus. ❋ Unknown (1918)
The arteries of the plexus are: (a) the anterior choroidal, a branch of the internal carotid, which enters the plexus at the end of the inferior cornu; and (b) the posterior choroidal, one or two small branches of the posterior cerebral, which pass forward under the splenium. ❋ Unknown (1918)
Its apex is situated at the interventricular foramen; its base corresponds with the splenium of the corpus callosum, and occupies the interval between that structure above and the corpora quadrigemina and pineal body below. ❋ Unknown (1918)
The Great Cerebral Vein (v. cerebri magna [Galeni]; great vein of Galen) (Fig. 565), formed by the union of the two internal cerebral veins, is a short median trunk which curves backward and upward around the splenium of the corpus callosum and ends in the anterior extremity of the straight sinus. ❋ Unknown (1918)
A sagittal section of the splenium shows that the posterior end of the corpus callosum is acutely bent forward, the upper and lower parts being applied to each other. ❋ Unknown (1918)
Medially, this surface is attached in front to the septum pellucidum; behind this it is fused with the upper surface of the body of the fornix, while the splenium is in contact with the tela chorioidea. ❋ Unknown (1918)
The central part (pars centralis ventriculi lateralis; cella) (Fig. 737) of the lateral ventricle extends from the interventricular foramen to the splenium of the corpus callosum. ❋ Unknown (1918)
The supracallosal gyrus is prolonged around the splenium of the corpus callosum as a delicate lamina, the fasciola cinerea, which is continuous below with the fascia dentata hippocampi. ❋ Unknown (1918)
The internal cerebral veins unite posteriorly in a single trunk, the great cerebral vein (vena magna Galeni), which passes backward beneath the splenium and ends in the straight sinus. ❋ Unknown (1918)
It begins near the occipital pole in two converging rami, and runs forward to a point a little below the splenium of the corpus callosum, where it is joined at an acute angle by the medial part of the parietoöccipital fissure. ❋ Unknown (1918)
It is placed beneath the splenium of the corpus callosum, but is separated from this by the tela chorioidea of the third ventricle, the lower layer of which envelops it. ❋ Unknown (1918)
The Hippocampal Fissure (fissura hippocampi; dentate fissure) begins immediately behind the splenium of the corpus callosum, and runs forward between the hippocampal and dentate gyri to end in the uncus. ❋ Unknown (1918)
