Practice question

Pick C: Have gap junctions permitting ion flow. Thinking about Synapse 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: cause and effect line up with Have gap junctions permitting ion flow — that is the mechanism or reason the stem is pointing to. Hence Have gap junctions permitting ion flow is correct. Treat this as a building block for the rest of Synapse; 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.
