Hormones: sources and key roles

What you’ll practice

Link major hormones to where they’re made (glands, organs, and tissues) and what they do in target organs. You’ll also sharpen your ability to recognize feedback loops and hormone “families” that sound alike but act differently.

Quiz format and difficulty

Each question has 4 options and there’s no timer, so you can reason through pathways without rushing. Set your preferred question count and choose a difficulty level; Mixed mode blends straightforward ID questions with scenario-style items for balanced challenge.

Common pitfalls to avoid

Many mistakes come from confusing similarly named hormones or mixing up endocrine vs. exocrine functions. Another frequent trap is assuming one hormone has only one job - several have multiple roles depending on tissue and context.

• Don’t swap pituitary “tropic” hormones with the hormones made by the target gland (e.g., TSH vs thyroid hormones).
• Watch for look-alike abbreviations (ACTH vs ADH; FSH vs LH).
• Separate hormone source from storage/release sites (especially in the hypothalamus–pituitary axis).
• Remember that some key hormones come from non-gland organs (kidney, heart, adipose tissue, GI tract).
• Use feedback logic: high end-hormone levels often suppress upstream signals.

Tips for better scores

Start with an easier set to lock in the core glands and hallmark effects, then increase difficulty to tackle regulation and clinical-style clues. If you miss a question, note whether the error was “source,” “role,” or “regulation,” and retest with a shorter focused run.
