   2.   Zona fasciculata
   3.   Zona reticularis
4. Which zone of adrenal cortex secretes “Androgens”?
   1.   Zona glomerulosa
   2.   Zona fasciculata
   3.   Zona reticularis
5. Identify the hormone: It is secreted in response to the decreased blood volume and pressure, acts on the kidney causing sodium and water retention to restore the blood volume and blood pressure.
   1.   Thyrotropin Releasing Hormone.
   2.   Aldosterone.
   3.   Calcitonin.
   4.   Parathyroid Hormone.
6. Identify the hormone: It is secreted by hypothalamus in response to the decreased blood concentration of T3,T4.

   2.   Aldosterone.
   3.   Calcitonin.
   4.   Parathyroid Hormone.
8. Identify the hormone: It is secreted in response to the decreased blood calcium levels, acts on bones to inhibit osteoblast activity, increases intestinal calcium absorption and stops calcium excretion from kidney to increase blood calcium levels.
   1.   Thyrotropin Releasing Hormone.
