In the figure, the neuronal membrane is at its resting potential at labelA.B.C.D.E.

It seems like you're referring to a specific figure related to neuronal membrane potentials. Unfortunately, I can't see images, but I can give you a general explanation about neuronal resting potential and potential labels.

Overview of Neuronal Resting Potential

1. Resting Potential: This is the electrical potential difference across the neuron's membrane when it is not conducting an impulse, typically around -70 mV inside the neuron relative to the outside.

2. Key Components:

   • Label A: Likely represents the inside of the neuron, which has a negative charge relative to the outside.
   • Label B: Could indicate the outside of the neuron, which is more positive in comparison.
   • Label C: Might refer to ion channels or pumps that help maintain resting potential, like the sodium-potassium pump.
   • Label D: This could represent specific ions (e.g., potassium or sodium) affecting the membrane potential.
   • Label E: Possibly indicates a change in potential when the neuron is stimulated (action potential), although this would not be at resting potential.

Summary

If you have specific labels or questions about how the resting potential works or data regarding those labels, feel free to elaborate, and I can provide more specific answers!
