  1. Which one of the following is the least involved in the function of endocrine glands?
    1. hormones
    2. ducts
    3. target cells
    4. receptors

  2. Thyroid hormones are the least directly involved in
    1. control of calorie expenditure and oxygen consumption
    2. control of body temperature
    3. control of sodium, potassium and chloride levels
    4. control of nervous system development and activity

  3. All of the following are true of parathyroid hormone except
    1. it is produced by several small parathyroid glands located in the neck
    2. it causes the intestines to absorb more calcium
    3. it causes the kidneys to excrete less calcium
    4. it causes bones to absorb calcium and incorporate it into bone tissue

  4. As an important part of the "stress response" that is activated during intense situations,
    1. the pancreas produces insulin
    2. the pituitary gland releases FSH and LH
    3. the adrenal medulla produces epinephrine
    4. all of the above

  5. During a prolonged "stress response," cortisol and other adrenal hormones
    1. cause fat and protein breakdown (to supply fuel to cells)
    2. reduce the excretion of sodium chloride and water by the kidneys (to conserve fluids for blood pressure)
    3. both of the above
    4. none of the above (cortisol and other adrenal hormones are not involved in the stress response)

  6. Insulin is produced mainly by cells located in the
    1. adrenal cortex
    2. pancreatic islets
    3. parathyroid glands
    4. anterior pituitary gland

  7. Which statement is true of insulin?
    1. its release is triggered by high blood sugar levels
    2. it enhances movement of glucose out of blood and into cells
    3. it stimulates glycogen and fat storage inside cells
    4. it lowers the blood sugar level
    5. all of the above

  8. If the glucose (blood sugar) level becomes too low,
    1. the liver may release a hormone that causes the pancreas to release glucose into the blood.
    2. the liver may release a hormone that causes the adrenal medulla to release glucose into the blood.
    3. the pancreas may release a hormone that causes the liver to release glucose into the blood.
    4. the kidneys may release a hormone that causes the pituitary gland to release glucose into the blood.

  9. In words such as "cortisol," "cortisone," etc., "cort-" refers to
    1. the anterior pituitary gland
    2. the exocrine part of the pancreas
    3. the outer part of the adrenal gland
    4. the inner part of the adrenal gland

  10. Whereas the _?_ has/have endocrine functions, the _?_ is/are exocrine.
    1. adrenal cortex / adrenal medulla
    2. thyroid gland / parathyroid glands
    3. pancreatic islets / pancreatic acini
    4. anterior pituitary / posterior pituitary

  11. what is the "highest priority" use of calcium?
    1. growth of bone tissue
    2. needed for production of thyroid hormones
    3. involved in long-term regulation of blood volume
    4. involved in cardiac action potentials (electrical functions of heart)

  12. Which gland has the greatest ability to "trap" and store iodine?
    1. pancreas
    2. thyroid gland
    3. adrenal gland
    4. posterior pituitary gland

  13. Which statement is true of the pituitary gland?
    1. It is attached to and controlled by the hypothalamus region of the brain.
    2. It secretes tropic hormones that affect the functions of other glands.
    3. It secretes human growth hormone and several other nontropic hormones.
    4. All of the above.
    5. None of the above.

  14. _?_ has the greatest potential to cause cells to absorb amino acids and produce protein.
    1. cortisol
    2. glucagon
    3. epinephrine
    4. human growth hormone (hGH)

  15. Usually, high levels of a hormone will result in
    1. target cells producing more receptors for that hormone
    2. a "spike" or "surge" in the production of other hormones
    3. reduction in the production of that hormone
    4. all of the above
