Unformatted text preview: c. There is a point during the action potential at which the inward flow of Na + is exactly balanced by the outward flow of K + . d. The resting membrane potential is set primarily by a leak K + conductance. e. Concentration changes of Na + and K + inside and outside the cell are the major players during an action potential. Action potential a. During the relative refractory period, there is still an outward K + current. b. The larger the length constant, the better the conduction properties of the cable. c. Decreasing the membrane resistance by wrapping the axon in a myelin sheath increases the speed of action potential propagation. d. The greater the cross-sectional area of an axon, the greater the speed of action potential propagation. e. The cell body has a smaller surface area to volume ratio than the axon....
