/.Which pancreatic cells release insulin and glucagon?

Acinar cells
Chromaffin cells
Chief cells
/.What hormone is made by the parafollicular cells of the thyroid gland?
Thyroxine (T4)
Triiodothyronine (T3)
Parathyroid hormone (PTH)
Calcitonin
Calcitonin is the hormone produced by the parafollicular C cells of the thyroid gland.
T3 and T4 are produced by follicular cells. PTH is produced by the parathyroid gland.
/.Which is not a main effect of the T3 (triiodothyronine) hormone?
Synergism with the sympathetic nervous system
Regulation of blood calcium levels
Promotion of growth and development
Regulation of the metabolic rate and thermoregulation
/.What stimulates the release of parathyroid hormone (PTH)?
Hypocalcemia
, Low basal metabolic rate
Hypercalcemia
Cold temperatures
Parathyroid hormone (PTH) is responsible for increasing blood calcium levels when the
levels drop too low. Therefore, a low level of blood calcium (hypocalcemia) is the
trigger.
/.Aldosterone regulates
blood calcium ion levels
blood glucose levels
blood iodide ion levels
extracellular sodium and potassium ion levels
Aldosterone regulates the blood sodium and potassium levels. It enhances sodium
absorption and potassium excretion through the kidneys.
/.What neurohormones are released from the adrenal medulla?
Corticosteroids
Androgenic steroids
Catecholamines
Glucocorticoids
/.What element is necessary for the production of triiodothyronine (T3) and thyroxine
(T4)?
Iodine
Potassium
Calcium
Magnesium
/.What hormones are produced by the zona glomerulosa of the adrenal cortex?
Neurohormones
Androgenic steroids
Glucocorticoids
Mineralocorticoids
/.Which hormone acts as a potent anti-inflammatory agent?
