Practice question
Question
Sacral plexus primarily supplies:
Explanation
Pick C: Posterior thigh and leg. Thinking about Peripheral 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 Posterior thigh and leg does in Peripheral Nervous System. Hence Posterior thigh and leg is correct. Treat this as a building block for the rest of Peripheral 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.
