Physioex Exercise 3 Activity 1 |Complete Solutions Graded A+ A negative membrane potential was recorded when the tip of the microelectrode was both inside the cell body and inside the axon which of the following caused a change in membrane potential from -70 to -40 in the cell body an increase in extracellular K+ Which of the following has the most negative voltage between the inside of the axon and the outside of the axon with control K+ ECF Explain why increasing extracellular K+ reduc...

Neurophysiology of Nerve Impulses. Physioex 31. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became less negative because les...
