Explanation:

Question 4

Melatonin is a hormone that regulates sleep - wake cycles. The pineal gland is responsible for its secretion. The thyroid gland is involved in metabolism regulation, the hypothalamus regulates various bodily functions and hormone release, and the anterior pituitary has multiple hormonal functions but not melatonin release.

Addison's disease is related to adrenal insufficiency. Common symptoms include hypotension (low blood pressure), bronze - like skin pigmentation, and electrolyte imbalance. Hyperglycemia (high blood sugar) is not a common symptom of Addison's disease; in fact, hypoglycemia can occur.

• For hyperthyroidism (overactive thyroid), Tapazole (methimazole) and Lugol's solution (iodine - based) are used to manage it. Tapazole inhibits thyroid hormone synthesis, and Lugol's solution can reduce thyroid hormone release.
• For hypothyroidism (underactive thyroid), Synthroid (levothyroxine) is a synthetic thyroid hormone replacement.

So the correct matches are:
Hyperthyroidism - 1. Tapazole; Hyperthyroidism - 3. Lugol's solution; Hypothyroidism - 2. Synthroid

Answer:

D. pineal
