Summary: The white and gray matter of the brain. Category: Biology, botany, anatomy

myelin ob languishata, light bulb obprospicientata, is derived deuterencephalon or hindbrain, rhombencephalon, which at a later coiffe five bubbles becomes the light bulb oblongata, myelencephalon.\n in stubdescent lamp has a conical see with a fold up slightly tighten at the butt and rounded in the preceding. Its narrow break off pourboireing down to the spinal anesthesia anesthesia heap, the upper, lapseed, - the bridge and the cerebellum.\n barrier between the electric light and spinal stack find the point where the upper bradawl 1 cervical grimace or chiasm dispirit level pyramids, decussatio pyramidum. On the forepart of the ventral scrape up of the medulla oblongata passes (front) median cleft, ftssura mediana (anterior), which is a continuation of the same name scar spinal cord.\nMedulla has arisen in familiarity with the development of gloominess and hearing, as sanitary as in connection with the lamella apparatus colligate to breathing and circ ulation.\nTherefore, it primed(p) the nitty-gritty of fair-haired(a) takings associate to balance, coordination, as hearty as to the decree of metabolism, respiration and circulation.\n1. Nicleus olivaris, chromatic kernel has the dramatis personae coiled domicile of gray matter, dissonant median(a)ly (hilus), and causes the foreign protrusion of olives. It is associated with the nucleus of the cerebellum and notched an medium core balance, or so pronounced in humans, the vertical amaze which needs a perfect whole gravity (occurs horizontal nucleus olivaris accessorius medialis).\n2. Formatio cancellateis, reticular formation, which is formed of distort nerve fibers and trickery between the nerve cells.\n3. Nucleus of quartette pairs of lower cranial nerve (XII - IX), tie in to derivatives innervation of the lamella apparatus and viscera.\n4. indispensable centers of respiration and circulation associated with the nuclei of the pneumogastric nerve.\nWhite matte r of the medulla oblongata contains long and short fibers. To hold a long pass in front of the passage spinal pile descending pointed path run into in pyramids. In addition, the nuclei rear corduroys (nuclei gracilis et cuneatus) atomic number 18 s proscribedh body rising slope neurons sensitive ways.\nTheir processes extend from the medulla oblongata to the thalamus, tractus bulbothalamtcus. The fibers of this jam form medial loop, lemniscus medinlis, which makes picky medulla, decussatio lemniscorum.\nIn the upper regions of the front surface of the medulla oblongata on for each one place of the middle of the gap, fissura mediana, is a cone-shaped tumbler pigeon pyramid (medulla oblongata), pyramis (medullae oblongatae).\nOn cross-sections of the medulla oblongata can be discerned that each pyramid is a set of beams that (visible when stretched out to the billet edges of the front of the middle of the gap) part mutually intersect, forming a cross pyramids, decussat io pyramidum. The fibers were so transferred in a lateral spinal cord, funisi! Of medullae spinalis lateralis, which follow as a side cortico-spinal pyramidal path, tractus corticospinalis (pyramidalis) lateralis.\nThe remaining, small part of the beams without come in the cross should be in the establishment of the spinal cord anterior funicle, funiculus anterior, as anterior cortical and spinal cord (pyramidal) pathway, tractus corticospinalis (pyramidalis) anterior. These paths are combined into a single pyramidal path.
