Hormone levels
🧪 Hypothalamic–pituitary–thyroid axis
TSH (pituitary)—
T4 (thyroid)—
Cortisol (adrenal)—
Glucose (blood)—
Heart rate—
Selected gland—
Note
A hormone is a chemical messenger carried by the BLOOD to target organs. Negative feedback keeps things stable: high T4 → loops back to "turn down" the hypothalamus & pituitary → TSH falls → the thyroid secretes less.
