HP-07 — 5 Must-Know Facts for NEET — Summary

Posterior pituitary trap: ADH and oxytocin are synthesised in the HYPOTHALAMUS (not posterior pituitary); posterior pituitary only stores and releases them.
GH age rule: GH excess in a child = gigantism (height increase, open plates); GH excess in an adult = acromegaly (no height increase, enlarged extremities, fused plates).
Calcium pair: Calcitonin (thyroid C-cells) LOWERS blood calcium; PTH (parathyroid glands) RAISES blood calcium — they are antagonists.
Adrenal cortex zones (GFR = Salt-Sugar-Sex): Glomerulosa = aldosterone; Fasciculata = cortisol; Reticularis = androgens; Medulla = adrenaline + noradrenaline.
Diabetes distinction: Type 1 DM = autoimmune β-cell destruction (no insulin); Type 2 DM = insulin resistance; Diabetes insipidus = ADH deficiency (normal blood glucose — completely unrelated to insulin).
