Action potential

Primary role of Na+/K+ ATPase in neurons is to:

Pick B: Critical limit. Thinking about Action potential in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: the functional job described in the stem is exactly what Critical limit does in Action potential. Hence Critical limit is correct. Treat this as a building block for the rest of Action potential; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Critical limit.

Action potential

Voltage-gated channels responsible for action potential are primarily located in:

The correct answer is C: Axons. In Action potential, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, the functional job described in the stem is exactly what Axons does in Action potential. That is why Axons is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
