Question details

QUESTION 15 Myocardial cells have long duration action potentials because of: gNa gK gCa gCI QUESTION 16 Currents in the Hodgkin-Huxley equations include: Na lc All of the above A and B only QUESTION 17 During the relative refractory period: A. Action potentials occur spontaneously OB. Action potential initiation can be accomplished by imposing a stronger stimulus Threshold is elevated OD. All of the above
QUESTION 6 Steady state inactivation can be decreased by: 0 A, Depolarizing conditioning voltage steps B. 5. Hyperpolarizing conditioning voltage steps No conditioning voltage steps D.none of the above QUESTION 7 Na current during the action potential decreases due to: decreased driving force increased driving force inactivation All of the above O A and C only QUESTION 8 In the squid axon experiments, the early inward current can be isolated by: O Treatment with TIN Treatment with alpha-bungarotoxin Treatment with TEA o Stepping to the Na equilibrium potential
