Nerve Regeneration
Topic: New ways to aid in nerve regeneration. General Purpose: To inform
Specific Purpose: To inform the audience about news techniques and mechanisms that aid in nerve regeneration. Central Idea Statement: The new techniques for nerve regeneration involving magnetic, electrical, and chemical mechanisms look very promising. ... They all have one thing in common: spinal nerve injury. ... Though the development of new antibiotics has greatly improved life expectancy, until recently medical science had not been able to restore nerve function. ... Research and treatment involving spinal and nerve injury has progressed considerably. ... When the spine is crushed or bent in an extreme accident, the spinal cord inside is severely bruised and compressed, causing localized injury and death to many of the nerve cells and their fibers. ... Nerve impulses are blocked at this point. ... The myelin is the part of the nerve that actually transfers the electrical signal that enables your muscles to move when you want them to move. ...
Keep in mind that not all nerves can regenerate (the spinal cord is a prime example) and if a nerve is too damaged or is severed it cannot come back C. ... The big problem with treating spinal injuries is the fact that mature nerve tissue does not spontaneously regenerate. ... The three basic ways to treat nerve damage are: first, produce regeneration of the remaining segment of a nerve fiber, or make new connections on the other side of the injury. Second, prevent or rescue the damaged nerve fiber from proceeding on to separation, or perhaps even functionally reunite the two segments, so that both portions of the fiber survive. Or third, facilitate nerve impulse traffic to cross the region of injury in intact fibers where they have lost their electrical insulation. ... The techniques that are being used to do this involve magnetic, electrical, chemical, or a combination of these to stimulate the damaged nerve. ... At present surgeons take a nerve from a less important part of the body and transfer it to the site of the injury. Generally the nerve is taken from the lower leg, but then sensation is lost in that portion of the body. ... What scientists currently want to learn, he said, is "the fundamental mechanisms that control whether nerve fibers grow and where they grow. ... from the University of
Illinois further states, "Imagine the end of a damaged nerve as a small child lost in a forest. ... Schmidt recently received a grant from the Whitaker Foundation to research ways to use electricity and an electrically conducting polymer material to stimulate nerve cell growth. ... This may mean supplying a tiny burst of electricity to stimulate the growth of a damaged nerve.
