What Do Peripheral Nerves Do

Peripheral Neuropathy Symptoms Resolved DavisSpineInstitute

When you first presented to the office, youpresented with chronic low back, leg pain, and neuropathy pain in your legs and feet.Your post surgical fusion patient and you had utilized a lot of different forms of therapyin pain management before coming to our office for help. How did you do with our therapyand how are you feeling today? Great, I don't have the pain down my leg, I have feelingin my feet now, I don't have that constant pain in the back. Well congratulations. We'revery proud of your results, and we're very proud to have you has a patient. Thank you.

Lab 9 Anatomy of the Peripheral Nervous System

gt;gt; This week in lab, we'regoing to continue our discussion of the nervous system,now moving away from the centralnervous system to talk about the peripheralnervous system. The peripheral nervoussystem will receive signals from the central nervous systemand bring that information out to the extremities. Will also bring sensoryinformation back.

And so we're going to talkabout those specific pathways. And we're going to identify anumber of nerves that assist in those functions orperform those functions. We're also going to talkabout a specialized branch of the nervous system calledthe autonomic nervous system. And the autonomic nervous systemis involved in control of many of the involuntaryfunctions of the body. And so our first taskthis week, in lab,

is to examine the spinalnerves and the nerve plexuses. Now in order to do that wewant to first look at where in the spinal cord dothese nerves come from? And so we need to look at theanatomy of these spinal nerves. We will then examine the anatomyof three specific plexuses. The cervical, brachial,and lumbosacral plexus. And in doing thatwe're going to identify which spinal nerves giverise to each plexus.

And which nerves arise asa result of those plexuses. And which structures are servedby those nerves ultimately. And we're going to talkabout both afferent and efferent branchesof those nerves. And so we're going to talk aboutmotor and sensory function. And then you'll do as wehave done all semester. Complete the workbook assignment with all resourcesavailable to you.

So the visible body softwarewill be of assistance here. The lab manual will help. And you might also want tovisit your Silverthorn textbook because some of the thingsthat we're going to talk about will be coveredin there as well. The second part of thelab, we're going to look at the autonomic nervoussystem and so again, we'll discuss the anatomyof both the parasympathetic

and sympathetic divisions ofthe autonomic nervous system. And again, there is a workbookassignment there for you to complete using boththe visible body software, the lab manual. And again, you might wantto visit your textbook and any other internet resourcesthat can help you with this. Pause So just a revisit from last weeka little bit, where we talked

Helping the body regrow nerves Science Nation

♫MUSIC♫ MILES O'BRIEN: Combat, cancer and accidents all can cause devastating nerve injuries. Sometimes, the body heals on its own. CHRISTINE SCHMIDT: Your peripheral nerves are the ones in the arms and the face, have an inherent ability to regenerate but only under ideal circumstances. MILES O'BRIEN: With support from the National Science

Foundation, University of Florida Biomedical Engineer Christine Schmidt is working to restore nerve function when injuries are more complicated. SURGEON: Took that muscle and rotated it, took it over the back of his elbow to cover – MILES O'BRIEN: Surgeons can sometimes move a nerve from one part of a patient's body to another. Schmidt has developed a method that grafts cadaver tissue onto the damaged area to

act as a scaffold for nerves to regrow themselves. CHRISTINE SCHMIDT: Basically what we're doing is removing all the cellular material that would cause rejection but leave behind the native architectures. You're putting this graft into the site of injury. And now, that graft is providing a scaffold for your blood vessels to grow in. And then once you have that recellerization your nerve fibers can then regrow, so then, ultimately regain that muscle function.

MILES O'BRIEN: Navy Veteran Edward Bonfiglio, wounded in Afghanistan, faced the prospect of an amputation. A graft was a welcome option. The company, AxoGen, distributes the grafts, which were developed based on work done in Schmidt's lab. JILL SCHIAPARELLI: And his family pressed the s to say, quot;Are there any alternatives?quot; He was a young, healthy, vibrant guy. And they had a great surgeon at Walter Reed who was willing to work with them to find those options.

CHRISTINE SCHMIDT: This is some of the micronized nerve that you're working with. MILES O'BRIEN: Schmidt and her team are also looking at other approaches to directly stimulate nerve growth using natural sugar molecules found in the body as building blocks, eliminating the need to transplant tissue. CHRISTINE SCHMIDT: So you don't have to actually take it from somebody's body. You can grow it.

MILES O'BRIEN: While the ultimate goal in nerve regeneration is reversing paralysis, Schmidt says intermediate successes, like improving lung or bladder function, can be invaluable to patients and their families. CHRISTINE SCHMIDT: So rather than saying we're going to try to tackle this humongously complex beast and try to get the patient to necessarily be exactly like they were before, why not provide some function that will have merit
