Question

which of the following pairs is mismatched?
a follicle - stimulating hormone—targets gonads
b prolactin—targets breasts
c thyroid - stimulating hormone—targets thyroid
d adrenocorticotropic hormone—targets adrenal medulla

Explanation:

• Follicle - stimulating hormone (FSH) acts on gonads (ovaries in females and testes in males) to regulate gamete production.
• Prolactin is involved in milk production in the breasts.
• Thyroid - stimulating hormone (TSH) targets the thyroid gland to regulate thyroid hormone synthesis and release.
• Adrenocorticotropic hormone (ACTH) targets the adrenal cortex, not the adrenal medulla. The adrenal medulla is regulated by the sympathetic nervous system.

Answer:

D. adrenocorticotropic hormone—targets adrenal medulla
