. The anatomy of the central nervous system of man and of vertebrates in general. Neuroanatomy; Central Nervous System. THE FOEM-EELATIONS OF THE HUMAN" BEAIN". 197 then accompanies the margin of the hemisphere still farther; curves with it into the temporal lobe, and ends only at its apex. The horizontal mass of transversely-divided fibers above the fornix belongs to the corpus callosum. On this there is distinguished anteriorly the genu, posteriorly the spleiiium, and between the two the body. Between the corpus callosum and the fornix lies the triangular field of the septum. Moreover, just in front of^and below the fornix the commissura anterior is seen in transverse section; it lies in the middle of the lamina terminalis. The lamina terminalis then continues ventrally into the floor of the inter- brain, and is here somewhat infolded by the chiasma—also cut Fig. 133.—Longitudinal section through the middle of an adult brain. The posterior portion of the thalamus, the crura cerebri, etc., have been removed, in order to expose the inner surface of the temporal lobe. These structures, in part membranous, have been purposely left intact in the preparation in order that the floor of the middle ventricle might be seen once more. The posterior wall—the infundibulum and its transition into the ventral region of the midbrain, the prominence of the tegmentum— has also been left in place. In your own preparations, however, remove all of these gray parts and observe how the fornix terminates behind the region designated as uncus. The portion of the wall of the hemisphere which lies above the corpus callosum is traversed by few and rather constant fissures. First of all, the sulcus cinguli runs parallel with the corpus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original wor
