Questions and Answers

Match the gland name with its labeled location on the diagram.

  1. Pancreas = G.
  2. Thyroid = E.
  3. Pituitary = A.
  4. Testis = I.
  5. Thymus = F.
  6. Hypothalamus = B.
  7. Pineal = C.
  8. Ovaries = J.
  9. Parathyroid = D.
  10. Adrenal = H.

Match the Hormone with the gland. Some will be used more than once.

  1. Calcitonin = e. Parathyroid Gland
  2. Catecholamines = a. Adrenal Gland
  3. Cortisol = a. Adrenal Gland
  4. Estrogen = c. Ovaries
  5. Glucagon = d. Pancreas
  6. Growth hormone = b. Anterior Pituitary Gland
  7. Insulin = d. Pancreas
  8. Oxytocin = f. Posterior Pituitary Gland
  9. Parathyroid hormone = e. Parathyroid Gland
  10. Prolactin = b. Anterior Pituitary Gland
  11. T3 & T4 = h. Thyroid Gland
  12. Testosterone = g. Testis

Match each Hormone with its main function.

  1. Insulin = e. Lowers blood glucose levels, regulating metabolism.
  2. Glucagon = g. Raises blood glucose levels.
  3. Oxytocin = a. Contracts uterine muscle during labor.
  4. T3 & T4 = b. Control metabolic rate and regulates growth and development.
  5. Calcitonin = c. Decreases plasma levels of calcium.
  6. Testosterone = h. Stimulates development of sperm and secondary male sex characteristics.
  7. Catecholamines = k. Stimulates the “fight, flight, or freeze” response.
  8. Growth hormone = j. Stimulates growth of bone and soft tissues.
  9. Parathyroid hormone = d. Increases plasma levels of calcium.
  10. Cortisol = f. Part of the stress response, also regulates glucose, fat, and protein metabolism.
  11. Estrogen = i. Stimulates development of the ova and secondary female sex characteristics.
  12. Prolactin = I. Stimulates the breast to develop and produce milk.
