Regeneration of Peripheral Nerve Fibers
Nerves can be easily damaged in a traumatic event due to their sometimes vulnerable positions in the body. However, if a nerve is damaged, it does have the ability to regenerate if its soma and a small portion of the neurilemma remain. The nerve begins the process by destroying the nerve distal to the site of injury allowing Schwann cells, basal lamina, and the neurilemma near the injury to begin producing a regeneration tube. Nerve growth factors are produced causing many nerve sprouts to bud. When one of the growth processes finds the regeneration tube, it begins to grow rapidly towards its original destination guided the entire time by the regeneration tube. Nerve regeneration is very slow and can take up to several months to complete. While this process does repair some nerves, there will still be some functional deficit as the repairs are not perfect.

Famous quotes containing the words regeneration of, regeneration, peripheral and/or nerve:
“Typically, the hero of the fairy tale achieves a domestic, microcosmic triumph, and the hero of myth a world-historical, macrocosmic triumph. Whereas the former—the youngest or despised child who becomes the master of extraordinary powers—prevails over his personal oppressors, the latter brings back from his adventure the means for the regeneration of his society as a whole.”
—Joseph Campbell (1904–1987)
“The republic, as I at least understand it, means association, of which liberty is only an element, a necessary antecedent. It means association, a new philosophy of life, a divine Ideal that shall move the world, the only means of regeneration vouchsafed to the human race.”
—Giuseppe Mazzini (1805–1872)
“If we are to change our world view, images have to change. The artist now has a very important job to do. He’s not a little peripheral figure entertaining rich people, he’s really needed.”
—David Hockney (b. 1937)
“The American people is out to get the kaiser. We are bending every nerve and every energy towards that end; anybody who gets in the way of the great machine the energy and devotion of a hundred million patriots is building towards the stainless purpose of saving civilization from the Huns will be mashed like a fly. I’m surprised that a collegebred man like you hasn’t more sense. Don’t monkey with the buzzsaw.”
—John Dos Passos (1896–1970)
