Question 1

Mineralocorticoids
(aldosterone)

Answer 1

• Secreting tissue: Zona glomerulosa (adrenal cortex)
• Targets the kidneys and
  blood
• Regulates mineral homeostasis; regulates blood pressure
  and volume; regulates blood pH

Question 2

Glucocorticoids
(cortisol)

Answer 2

• Secreting tissue: Zona fasciculata (adrenal cortex)
• Target tissue: Diffuse (most body tissues)
• Regulates carbohydrate metabolism, helps provide resistance to stress, anti-inflammation

Question 3

Androgens (DHEA)

Answer 3

• Secreting tissue: Zona reticularis (adrenal cortex)
• Target tissue: Diffuse (brain, gonads, bone)
• Promotes libido, stimulates phenotypic changes associated with puberty

Question 4

Catecholamines
(epinephrine &
norepinephrine)

Answer 4

• Secreting tissue: Adrenal medulla
