Practice question

Pick B: Surface area. Thinking about Structure and Function of Nervous System 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 Surface area does in Structure and Function of Nervous System. Hence Surface area is correct. Treat this as a building block for the rest of Structure and Function of Nervous System; 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.
