Question

Number each of the following in order of its numerical value in mV, with 1" being the greatest. Vm of neuron in axonal region Y that is adjacent to and downstream from X, at the time after its membrane potential has begun to respond to the depolarization at X, but before a depolarization at Y has been triggered Vm of neuron prior to stimulation of depolarization Vm of neuron in a region X of the axonal membrane where a depolarization has been stimulated, at the time when Na+ permeability is at its peak Vm of neuron in a region X of the axonal membrane where a depolarization has occurred and the relevant Na+ and K+ channels have closed again, but the Na/K ATPase and K+ leak channels have not yet restored the resting Vm B V of neuron in a region X of the axonal membrane where a depolarization has been stimulated, at the time when K+ permeability is rising and Na+ permeability is falling Submit Answer Tries 0/3

Explanation / Answer

Option 3rd will be 1.

Option last will be 2

Option first will be 3

Option 2nd will be 4 and

Option 4th will be 5.

At the resting stage the membrane potential is -70mV which rises as depolarization starts and maximum value occurs when Na ion permeability is at peak (+40mV). Again voltage starts to get down as reploarization starts. Repolarization continues up to -90mV which again becomes -70mv slowly. The permeability of sodium ions increases with depolarization and maximum at 40 mV. After this repolarization starts and again potential starts to get down but continues upto -90mv which becomes -70mv.
