Lec9 - 2007 INTRODUCTORY ANIMAL PHYSIOLOGY BIOAP 311/VETBM 346 FALL 2007 OUTLINE - LECTURE 9 Conduction of Action Potentials (Readings - Chapter 3 - pp 37-41) I. Major Topics/Concepts to be covered: 1. Sub-threshold potentials vs. all-or-none action potentials. 2. Local circuit theory of action potential conduction. 3. Cable properties of nerve axons. 4. Determinants of action potential velocity. 5. Saltatory conduction and Myelination. II. You will have learned the material when you can: 1. Explain the relationships between local circuit currents, ion flow, threshold, and axon cable proper- ties. 2. Relate action potential speed to axon cable properties

Would decreasing the internal resistance of an axon increase or decrease action potential velocity? 2. How does potassium permeability during an action poten-tial influence conduction velocity? 3. What is the difference between conduction velocity and transit time? 4. How would temperature change affect conduction velocity? 5. Does decreasing the diameter of an axon increase or decrease the internal axon resistance? file:///C|/WINWORD/COURSES/31107/Lec9-07.HTM8/15/2007 10:16:56 AM...
