Practice question

Pick B: Basement membrane. Thinking about Tissue-I 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: excitable-cell physiology turns on membranes, ions, and signalling steps, and Basement membrane captures the correct piece of that story. Hence Basement membrane is correct. Treat this as a building block for the rest of Tissue-I; 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 Basement membrane.
