current is directed over the nerves that lead to those electrodes so that a computer can record and evaluate the consequent nerve impulse for velocity‚ onset and amplitude. Neuropathies are caused by damage to the nerves axon and/or damage to the myelin sheath surrounding the nerve. If a response is slower than normal‚ damage to the myelin sheath is implied. If the height of the response’s amplitude is low with a relatively normal speed of conduction‚ damage to the nerve axon is implied. How

Nuttel has a medical condition that has to do with his nerves. Mr. Nuttels nerves are very easily damaged. His nerves cause him to have breakdowns when he gets scared or something. Mr. Nuttels condition in the house was bad because Vera told him a story that got him nervous. He thought he was seeing ghost but it was just the story Vera told him. Mr. Nuttels condition was very serious because he could have had a heart attack from his nerve condition or possibly even worse than that. Mr. Nuttel was

spinal cord‚ and the nerves. The nervous system enables a way for the brain to receive information about someone’s surrounding. Then‚ the brain is able to send signals to various areas of the body‚ so it can respond. Millions and millions of cells called neurons creates the nervous system. “Specialized neurons called receptors are located in the ears and eyes and the other sense organs of the body. The receptors translate events in a person’s surroundings . . . into nerve messages‚ which are known

Most professional baseball pitchers can throw a fastball over 145 km/h (90 mph). This gives the batter less than half a second to read the pitch‚ decide whether to swing‚ and then try to hit the ball. No wonder hitting a baseball is considered one of the hardest things to do in sports! 1. What

II-Needle Electromyography: Is complements nerve conduction studies and serves a critical role in the evaluation of both muscle and nerve diseases. Recording the electrical activity of the muscle cell membrane with a needle electrode inserted in the muscle‚ the motor unit potential (MUP) can be recorded. Electromyography is performed using an instrument called electromyograph‚ to produce a record called electromyogram. This represents the summated electrical activity of action potentials of all

the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells. In some cases they have been known to attack the axons themselves. The first known incident of Guillain-Barre syndrome was reported in 1859 by a Frenchman named Jean Baptiste Octave Landry
