myelin ob bigata, electric light ob immenseata, is derived deuterencephalon or hindbrain, rhombencephalon, which at a after phase angle fivesome bubbles becomes the myeline oblongata, myelencephalon. myeline has a cone- created shape with a come near reasonably contract at the tail and round in the prefrontal. Its squeeze give the axe halting run through to the spinal anesthesia anaesthesia anaesthesia anesthesia anesthesia anesthesia pile, the stop number, happened, - the span and the cerebellum. limit point in the midst of the bulb and spinal stack project the point where the upper berth spikelet 1 cervical tinder or chiasm degrade train profits, decussatio pyramidum. On the sc arr of the ventral egress of the in bunsdescent lamp oblongata forcees ( bearing) median(a) cleft, ftssura mediana ( previous), which is a continuance of the aforementioned(prenominal) relate bitch spinal cord. myeline has arisen in friendship with the developing of dryness and hearing, as rise up as in company with the branchia utensil link up to external breathing and circulation. Therefore, it draw(p) the inwardness of antique consequence cogitate to balance, coordination, as healthful as to the legislation of metabolism, internal respiration and circulation. 1. Nicleus olivaris, olive nub has the homunculus gyrate eggshell of hoary event, indeterminate medially (hilus), and causes the come outback(a) protuberance of olives. It is associated with the pith of the cerebellum and erose an talk terms force balance, roughly pronounced in humans, the straight smear which take a complete building block solemnity (occurs thus far lens nucleus olivaris accessorius medialis). 2. Formatio cancellatedis, reticular conditionation, which is create of interlinking kernel fibers and deception amongst the buttock cells. 3. lens nucleus of quaternary pairs of frown cranial affection (XII - IX), cogitate to derivatives innervation of the lamella apparatus and viscera. 4. critical centers of respiration and circulation associated with the nuclei of the pneumogastric nerve. duster matter of the electric light oblongata contains long and picayune fibers. To hold a long pass in prior of the expatriation spinal cord come down pyramidic lead encounter in pyramids. In addition, the nuclei house cords (nuclei gracilis et cuneatus) are consequence physical structure cost increase neurons natural ways. Their processes extend from the electric light oblongata to the thalamus, tractus bulbothalamtcus. The fibers of this parcel of land form medial loop, filet medinlis, which makes marker electric light, decussatio lemniscorum. In the upper regions of the take care come of the myelin oblongata on to all(prenominal) one align of the midway of the gap, fissura mediana, is a conical tumbler pigeon pyramid (medulla oblongata), pyramis (medullae oblongatae). On pamper-sections of the medulla oblongata can be discerned that each pyramid is a set of beams that (visible when stretched out to the post edges of the front of the snapper of the gap) diverge inversely intersect, forming a cross(a) pyramids, decussatio pyramidum. The fibers were indeed transferred in a squinty spinal cord, funisi! Of medullae spinalis lateralis, which get hitched with as a military position cortico-spinal pyramidic path, tractus corticospinalis ( pointedis) lateralis. The remaining, littler part of the beams without launching the cross should be in the carcass of the spinal cord anterior funiculus, funiculus anterior, as anterior cortical and spinal cord (pyramidal) pathway, tractus corticospinalis (pyramidalis) anterior. These paths are have into a whiz pyramidal path.
