Which statement about tropic hormones is true?

Which statement about tropic hormones is true?

• A. They act on peripheral tissue.
• B. They act on other endocrine glands.
• C. They are produced by the pituitary gland only.
• D. They do not interact with target organs.

Answer: (B)

Tropic hormones are signals whose main job is to regulate another endocrine gland. They tell glands such as the thyroid, adrenal cortex, and gonads when to secrete their hormones and often influence the growth of those glands. That direct action on other endocrine organs is what makes the statement true. They don’t primarily target peripheral tissues, and they do interact with their target organs by triggering hormone production or gland growth. While many tropic hormones come from the pituitary, the essential point is their action on other glands, not just where they’re produced.
