1. Which hormone is secreted by the anterior pituitary to
stimulate thyroid hormone production?
A. Thyroid-stimulating hormone (TSH)
B. Adrenocorticotropic hormone (ACTH)
C. Luteinizing hormone (LH)
D. Follicle-stimulating hormone (FSH)
Correct Answer: A. Thyroid-stimulating hormone (TSH)
Rationale: TSH acts on the thyroid gland to produce T3 and T4.
2. Which hormone increases calcium levels in blood by
stimulating osteoclasts?
A. Parathyroid hormone (PTH)
B. Calcitonin
C. Calciferol
D. Insulin
Correct Answer: A. Parathyroid hormone (PTH)
,Rationale: PTH promotes calcium release from bones and increases
absorption.
3. Which hormone decreases blood calcium by promoting
osteoblast activity?
A. Calcitonin
B. Parathyroid hormone
C. Vitamin D
D. Aldosterone
Correct Answer: A. Calcitonin
Rationale: Secreted by the thyroid gland’s parafollicular cells.
4. Which hormone increases sodium reabsorption and potassium
excretion in kidneys?
A. Aldosterone
B. ADH
C. Cortisol
D. Epinephrine
Correct Answer: A. Aldosterone
Rationale: Mineralocorticoid regulating electrolyte balance.
5. Which hormone increases water reabsorption in kidneys?
A. Antidiuretic hormone (ADH)
B. Aldosterone
C. Renin
,D. ANP
Correct Answer: A. Antidiuretic hormone (ADH)
Rationale: Inserts aquaporins in collecting ducts to retain water.
6. Which hormone stimulates adrenal cortex to produce cortisol?
A. Adrenocorticotropic hormone (ACTH)
B. TSH
C. Growth hormone
D. Prolactin
Correct Answer: A. Adrenocorticotropic hormone (ACTH)
Rationale: ACTH regulates glucocorticoid secretion from the
adrenal cortex.
7. Which hormone increases glucose levels in blood during
fasting?
A. Glucagon
B. Insulin
C. Cortisol
D. Epinephrine
Correct Answer: A. Glucagon
Rationale: Secreted by pancreatic alpha cells to promote
glycogenolysis.
8. Which hormone decreases blood glucose by promoting cellular
uptake?
, A. Insulin
B. Glucagon
C. Cortisol
D. Epinephrine
Correct Answer: A. Insulin
Rationale: Secreted by pancreatic beta cells; lowers blood sugar.
9. Which hormone regulates circadian rhythm?
A. Melatonin
B. Cortisol
C. Thyroxine
D. ADH
Correct Answer: A. Melatonin
Rationale: Produced by the pineal gland, signaling day-night cycles.
10. Which hormone is secreted in response to stress to increase
glucose?
A. Cortisol
B. Insulin
C. Glucagon
D. Aldosterone
Correct Answer: A. Cortisol
Rationale: Glucocorticoid promoting gluconeogenesis and anti-
inflammatory effects.
