B
Thyroid stimulating hormone signals the thyroid gland to release the hormone thyroxin.

검증된 단계별 안내1
Understand the definition of a tropic hormone: Tropic hormones are hormones that have other endocrine glands as their target. They stimulate these glands to release other hormones.
Identify the function of each hormone mentioned: Insulin regulates blood sugar levels, epinephrine causes physiological changes, estrogen can pass through cell membranes, and thyroid stimulating hormone (TSH) signals the thyroid gland.
Determine which hormone fits the definition of a tropic hormone: TSH is the hormone that targets another endocrine gland (the thyroid) to release thyroxin.
Recognize that tropic hormones are part of a regulatory system in the body, often involved in feedback loops to maintain homeostasis.
Conclude that thyroid stimulating hormone is the correct example of a tropic hormone, as it directly influences the activity of another gland.
