Practice questions testing deep understanding of hormone mechanisms, feedback loops, and gland interactions.
Q1. Hormones like Insulin and Glucagon are protein-based (peptide) hormones, while Testosterone and Estrogen are steroid (lipid-based) hormones. Explain how this biochemical difference fundamentally changes the way these two types of hormones interact with their target cells.
Q2. The Hypothalamus and the Anterior Pituitary gland are physically connected, but they communicate entirely via a portal blood system. In contrast, the Hypothalamus and the Posterior Pituitary communicate via direct neural connections. Explain the functional consequence of this anatomical difference.
Q3. Assertion (A): The parathyroid hormone (PTH) is hypercalcemic. Reason (R): Whenever blood calcium levels drop, PTH is released. It forcefully extracts calcium from the bones (demineralization) and releases it into the blood to raise the calcium levels back to normal.
