Title: Describe the significance of using 9mM sodium chloride inside the cell and 6 mM
Post by: whitecaddy26 on Feb 18, 2011
I am struggling with my PhysioEx. 8.0.  On the review sheets for exercise 3. I am in need of help for the following questions. 4. What is the difference between membrane irritability and membrane conductivity? 5. Why does a nerve's action potential increase slightly whan you add 1.0V to the threshold voltage and stimulate the nerve? 13. What is the relationship between size of a nerve and conduction velocity? 14. keeping your answer to question 13 in mind, draw an analogy between the nerves in the human body and electrical wires. 15. Hypothesize what types of animals would have the fastest conduction velocities.16. How does myelination affect nerve conduction velocity? Explain. 17. 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. Any help would be wonderful!!!
