Problem 21.81 3 of 3 I Review The speed with which nerve impulses travel is determined in large part by the characteristic time constant T = RC of the circuit formed by the resistivity of the axon and the capacitance of its wall. The resistance of a 1.00-mm-long segment of an axon is 26.0 M92. Part A For nerve axons with no protective myelin sheath, the wall capacitance...
