Guest guest Posted January 5, 2006 Report Share Posted January 5, 2006 hi, all, so can the nerve cell or fiber regenerate if it is destroyed or damaged? Muscle relaxes and contracts due to stimulation from nerve. Nerve secrets hormone to stimulate the muscle cell so that causes a series of cell co-operation and coodination occurs. This will cause muscle to relax or contract. Those hormones secrets by the nerves contain some sort of electron and proton and when they accumulate to a level, and sudden discharge happens, this process is called " depolarization " . The depolarization initiates the cell mechanical contraction and relaxation and it is spread and proprogate from cell to cell. this is where the wave or Peristalsis comes from. our brain is the central control of our nerve system. When we eat, our brain send " signal " to nerve thru our spinal cord. Nerver gets the signal and start secrete hormone that causes the entire swallowing mechanism. some of the muscle movement can be controlled by our mind. This kind of muscle movement is voluntary and other is not controlled by our mind is involuntary or intrinsic. Peristalsis is intrinsic or involuntary. if the nerve is totally gone, for some unknown reason, we cannot swallow anything at all. we need to go for a myotomy to remove the LES so that food can move down to our stomach, or figure out a way so that those nerve can be regenerated. Vitamin B can help us maintain healthy nerve system, also it can help nerve regeneration. This is why some people (in the poll section) found out taking Vitamin B help reduceing Achalasia symptoms. if the nerve is still there, that means something wrong happens in coordination of our brain, nerve system, hormone secretion and muscle. A lot of factors can negatively affect any or multiple system. I believe we need to figure out those factors. I am kind of changing my life style, eating habbit and improve my emotion while undergoing an acupuncture treatment. and I am trying my best to reduce or manage my stress. Also I am taking VB daily now. I will keep you guys updated. Thank you. Quincia > Achalasia does not permanently damage the nerves, it just makes them misfire and under the correct pH the nerve will operate correctly again. > > I am a bit confused by this statement. I have always heard that achalasia is the result of nerves being destroyed/lost. I've even seen pictures of destroyed nerve cells. And literature explaining this part of achalasia is plentiful (see examples below). > > So I guess I'm not sure if you're saying that ALL achalasia is caused by a pH problem, or if this is just the case in your own personal situation, but not necessarily the case for others with achalasia??? Or are you saying that *all* the doctors are wrong and that the nerves that are destroyed really haven't been destroyed? > > Can you elaborate on this? > > Debbi in Michigan > -------------------------------------------------------------------- ------ > > For unknown reasons, in patients with achalasia, an inflammatory reaction targets nerve cells in the esophagus, particularly those that signal the LES to relax. This reaction causes these cells to gradually disappear. The end result is that the LES fails to relax and thereby creates a blockage for swallowed material to enter the stomach. To make matters worse, nerve cells in the lower two-thirds of the esophagus are also destroyed. > (from http://patients.uptodate.com/topic.asp?file=digestiv/4384 ) > > > There is a loss of nerve cells in the Auerbach plexus between the two muscle layers of the esophageal wall and in the lower esophageal sphincter.

The disease results from a neurologic deficit in the myenteric plexus. There is a marked decrease in myenteric ganglion cells with marked inflammatory changes.3 The lower esophageal sphincter dysfunction is due to the destruction of inhibitory nerve fibers which normally reduce sphincter tone and control sphincter relaxation. Their absence leads to poor reduction of the sphincter's resting tone. The cause of the disorder is unknown.4 > (from http://www.clevelandclinicmeded.com/diseasemanagement/gastro/motor/mot or.htm#ppathophysiology ) > > > Primary achalasia is the most common subtype and is associated with loss of ganglion cells in the esophageal myenteric plexus. > (from http://www.emedicine.com/radio/topic6.htm#section~introduction ) > > > The muscle and nerve components of the esophagus are abnormal. The primary defect appears to be a progressive loss of ganglion cells within the myenteric plexus of the esophageal wall. > (from http://www.merck.com/mrkshared/mmg/sec13/ch105/ch105c.jsp ) > > > The principal lesion is denervation of the oesophageal smooth muscle.7 While muscular abnormalities are also present, these appear to be secondary to the neural deficit. A decreased number of ganglion cells in the oesophageal intramural nerve plexus has been found in patients with achalasia, and the extent of this loss corresponds to the duration of the disease.8,9 There may also be degenerative changes in the vagus nerve, both in its branches to the oesophagus and in the dorsal motor nucleus.10 The interaction between nerve plexus and vagus nerve lesions is not yet clear.8 In both cases, the loss predominantly concerns inhibitory neurons. 8,9,10 This would explain the increased basal LOS pressure as well as the inadequate sphincteric relaxation observed on swallowing. Degeneration of the oesophageal ganglion cells leads to permanent aperistalsis as the disease progresses and favours oesophageal dilatation.7 (from http://www.tcd.ie/tsmj/2003/achcardia.htm ) > > > Studies show that the nerves that control the muscle contractions of the esophagus have deteriorated. > (from http://www.intelihealth.com/IH/ihtIH/WSIHW000/9339/9405.html ) > Quote Link to comment Share on other sites More sharing options...
