What is the concentration of K/Na inside the membrane of a neuron during resting
potential?

[oxoracoon11]

There is no single defenitive answer but during resting potential, the concentration of potassium is high, 140-155 mM. While sodium is fairly low, around 10-15 mM.

The rules tell you that you should "understand" the list of disorders in each section. At a minimum, I'd include: What is it, what causes it, what happens at a cellular level in the disorder, what are the diagnostic criteria, how does the disorder progress (stages, timescales), what are the practical effects that the disorder has on people, what therapies or treatments exist to help manage the disorder, and how do they work, is there scope for future treatments, and so on.

As for how deep you need to go, I'd say don't stop learning. A&P tests can get quite specific. When you're confident at one level, go another step deeper.
