When first formed, the hemispheres are slight evaginations from the median portion of the telencephalon, the openings by which their cavities communicate with the third ventricle, the interventricular foramina, being relatively very large (Fig. 240), but, in later stages (Fig. 233), the hemispheres increase more markedly and eventually surpass all the other portions of the <y. ââ¢â / Fig. 240.âMedian Longitudinal Section of the Brain of an Embryo of mm. br, Anterior brachium; eg, corpus geniculatum laterale; cs, corpus striatum; h, cerebral hemisphere; ir, infundibular recess; It, lamina terminalis; or, optic recess; ot, thalamus; p, pineal process; sm, sulcus Monroi; st, hypothalamic region; vi, velum interpositum.â(His.) brain in magnitude, overlapping and completely concealing the roof and sides of the diencephalon and mesencephalon and also the anterior surface of the cerebellum. In this enlargement, however, the interventricular foramina share only to a slight extent, and consequently become relatively smaller (Fig. 233), forming in the adult merely slit-like openings lying between the lamina terminalis and the thalami and having for their roof the anterior portion of the velum interpositum.
