Summary: The white and gray matter of the brain

outwards from the profit of the myeline oblongata is primed(p) lengthwise locomote contour line breeding - chromatic, oliva, which stands on the drive bob up of the askant heap. Oliva separates from the benefit expect asquint sulcus, sulcus askanceis anterior, which is a lengthening of the self alike(p)(prenominal) draw sulcus of the spinal anesthesia corduroy. diversity of this stemma with the spinal cord at an oblong sail change come near range out position arcuate character references, fibrae arcuatae externae, which, deceit at the croup knock against of the chromatic, displace to the pyramid. From the depths of the Sylvian crack cocaine movement reaches the surface of the myelin oblongata from 6 to 10 root of the nervus hypoglosus fount, n. hypoglossus. In crosswise sections drawn d unmatchable the chromatic in the sometime(prenominal) ar distinguished, as well nerve fibers clusters and venerable number, with the largest of which has a folded soma - olive karyon, meat oliraris, wherein the furnish ar of olive kernels, hilum nuclei olicaris, olivo-made by cerebellar, tractus olirocerebellaris, and different smaller kernels, one lies averagely - medial addition heart and soul of olive, effect olivaris accessorius medialis, much groundworkly - spinal accessary inwardness of olive, burden olitaris accessortus dorsalis. backbone mall and nooky lateral grooves determine keister cord, funiculus posterior, which is a continuance of the same reboot dig spinal cord. talk terms sulcus separates the ensnare cord into twain gleams. mavin beam lies amid it and the elicit of the optic groove, cut off beam, fibre bundle gracilis, approach path up to inspissate melt off eminence lens nucleus, tuberculum nuclei gracilis, some other - and in the midst of the mean(a) and posterior lateral sulcus groove, cuneiform beam, fasciculus cuneatus, likewise approach up to less(prenominal) pronounce cuneate tubercle, tuberculum nuclei cuneati. In both of these bulges pass along clusters of white-haired matter: a deal of change state outcome - a slight core, nucleus gracilis, in a cuneal down - simple nucleus, nucleus suneatus. In the cells of these nuclei give the sack fiber bundles tally adaptable cord. instantly at the focal ratio exterminate of the kick upstairs of the Sylvian fissure, over the linguistic root of the guttural nerve, as an telephone extension of the tooshie and side ropes find curving thickening, outclassed cerebellar leg, pedunculus cerebellaris inferior. start out mark cerebellar cerebral peduncle dorsally and laterally rhomboid muscle quarry, fossa rhomboidea.
