Action potential

Local potentials mainly occur at:

Pick C: Dendrites and cell body. 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 Dendrites and cell body does in Action potential. Hence Dendrites and cell body 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.

Action potential

Absolute refractory period occurs because:

Go with B — Na+ channels remain inactivated. Within Action potential, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, cause and effect line up with Na+ channels remain inactivated — that is the mechanism or reason the stem is pointing to. Holding that picture in mind makes Na+ channels remain inactivated feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Na+ channels remain inactivated.
