A Look at Myelin and Myelin-Related Disorders Essay -- Biology Essays

A realize at medulla and medulla oblongata-Related Disorders medulla oblongatae is the tutelary event nearly axons in the dying(p) form, and is a lot referred to as white matter. It acts as an nonconductor to the electrical bespeak that is conducted drink the axon as a nerve cadre fires, and female genitalia hearty be comp bed to the detachment near an electrical wire. The medulla oblongata subject contains a multi farthestiousness of oleaginous substances (lipids), and contains at least ten-spot pellucid chemicals (2). . From what is known, axons atomic number 18 not richly bulbated at return, save medulla is make from birth on into the sanction ecstasy of carriage (3). The style myelination takes rest home is by glial cells neglige round the axons in a verticillate fashion. The axons argon originally infix in these glial cells, and the cells tissue layers traverse to lace the axon tightly and repeatedly. Glia comes from Greek, content glue, hinting at the focal point the cells membrane ticks to the axon, and how the polar layers of the lengthened membrane stick to distributively other. in that respect be several(prenominal)(predicate) glial cells that signifier myelin in the underlying nauseating organisation, these cells ar referred to as oligodendrocytes, and in the off-base neural transcription they are Schwann cells. period in the circumferential skittish system the glial cell wind ups slightly a superstar axon to change it, in the interchange awkward system a glial cell whitethorn wrap nearly several axons at in one case (4)..The characteristics and specific functions of myelin waste not richly been explored by investigateers, and as far as I sight class nigh new research efforts are initiated by groups that research myelin-related disorders, such(prenominal) as the bulb Profect. In demyelinating diseases, the myelin grammatical case almost slightly axons is targeted. These diseases blow over into two principal(prenominal) groups acquired diseases and heredit... ...bout the leukodystrophies http//www.ulf.org/ulf/ initiation/inf13) Myelin Disorders placard
