Most Tested Concepts (Frequency Analysis)

Rank 1 — ADH/Oxytocin synthesis site (3+ appearances: 2019, 2021, 2023) Question type: "Where are ADH and oxytocin synthesised?" Always-correct answer: Hypothalamus (supraoptic and paraventricular nuclei). Posterior pituitary = trap answer (storage site only).

Rank 2 — Acromegaly vs gigantism (2018, 2022 + similar patterns) Question type: Adult patient with enlarged extremities and facial features but no height change — diagnosis? Always-correct answer: Acromegaly. Key discriminator: adult + fused growth plates = no height increase.

Rank 3 — Calcium regulatory pair (2020, 2024) Question type: "Which hormone raises blood calcium?" or "Identify the antagonistic hormone pair for calcium." Always-correct answers: PTH raises; calcitonin lowers. Sources: PTH = parathyroid; calcitonin = thyroid C-cells.

Rank 4 — Adrenal cortex zones (recurrent) Question type: "Which zone produces aldosterone/cortisol/androgens?" Always-correct answer: Use GFR = Salt (Glomerulosa), Sugar (Fasciculata), Sex (Reticularis).

Rank 5 — Diabetes types comparison (recurrent) Question type: "Which type involves autoimmune destruction?" or "Which type involves insulin resistance?" Always-correct answers: Type 1 = autoimmune β-cell destruction, insulin-dependent; Type 2 = insulin resistance.

Strategic Tips

• High-yield topics for guaranteed marks: ADH synthesis site, acromegaly vs gigantism, calcium hormones, GFR mnemonic, FLAT PG mnemonic, DM types.
• Most traps exploit: confusing source with storage site, age-dependent manifestations, and antagonist reversal.
• For any hormone question: first identify the gland → then the zone/cell → then the chemical class → then the mechanism of action. This systematic approach eliminates all distractors.
