Title: PhysioEx 8.0 Exercise 3 question 17 Post by: whitecaddy26 on Feb 27, 2011 I need help with this question, please!!
In the nerve conduction velocity experiment, if any of the nerves used were reversed in their placement on the stimulating and recording electrodes, would there be any differences seen in conduction velocity? Explain. Thanks!!! Title: Re: PhysioEx 8.0 Exercise 3 question 17 Post by: duddy on Feb 27, 2011 Mine goes up to question 16... :s

Title: Re: PhysioEx 8.0 Exercise 3 question 17 Post by: gee.amanda on Feb 27, 2011 No because the same conduction exists

No. Once a neural membrane is depolarized and the impulse is being conducted along the neural membrane, which direction is which does not matter. We state that a neural impulse is set up in the neuron’s trigger zone (mainly due to the large number of sodium channels there) but once the depolarization is set up, it not only travels down the axon but also around the soma of the cell.

THANKS so much I needed this too, can't wait till reading week llolNo. Once a neural membrane is depolarized and the impulse is being conducted along the neural membrane, which direction is which does not matter.
