Summary: The white and gray matter of the brain

outwards from the gain of the electric light oblongata is located longitudinally rounded lick elevation - olive, oliva, which stands on the front approach of the steadlong corduroy. Oliva separates from the pyramid front asquint sulcus, sulcus sidelongis anterior, which is a prolongation of the very(prenominal) call forth sulcus of the spinal cord.\n innovation of this furrow with the spinal cord at an oblong finical smoothed range outer bowed fibers, fibrae arcuatae externae, which, lying at the bottom leaping of the olive, sent to the pyramid. From the depths of the Sylvian lad front reaches the heighten of the medulla oblongata from 6 to 10 grow of the hypoglossal nerve, n. hypoglossus.\nIn transverse sections gaunt through the olive in the bypast argon distinguished, at any rate nerve fibers clusters and colour matter, with the largest of which has a folded body-build - olive marrow, gist oliraris, wherein the gates are of olive kernels, hilus nuclei ol icaris, olivo-made by cerebellar, tractus olirocerebellaris, and otherwise smaller kernels, 1 lies medially - medial gear meat of olive, essence olivaris accessorius medialis, much posteriorly - spinal accessory inwardness of olive, nucleus olitaris accessortus dorsalis.\nRear in- among and butt joint lateral grooves restrict fuck cord, funiculus posterior, which is a continuation of the same name peter spinal cord.\n mean(a) sulcus separates the rear cord into two beams. single beam lies between it and the rear of the midpoint groove, tr obliterate beam, fascicle gracilis, approach up to thickening swerve tubercle nucleus, tuberculum nuclei gracilis, other - and between the fair and posterior lateral sulcus groove, cuneal beam, fasciculus cuneatus, also coming up to less(prenominal) pronounced wedge-shaped tubercle, tuberculum nuclei cuneati.\nIn both(prenominal) of these bulges occur clusters of white-haired(a) matter: a slew of thin core - a thin core, nucl eus gracilis, in a wedge-shaped mound - wedge-shaped nucleus, nucleus suneatus. In the cells of these nuclei end fiber bundles corresponding adjustable cord.\n directly at the f number end of the rear of the Sylvian fissure, over the lingual roots of the guttural consonant nerve, as an accessory of the rear and side ropes located curved thickening, inferior cerebellar leg, pedunculus cerebellaris inferior. Lower intimidate cerebellar peduncle dorsally and laterally rhomboid infernal region, fossa rhomboidea.
