Answer: Corticoids.
- A Catecholamines
- B Sex steroids only
- C Corticoids
- D Thyroid hormones
Correct answer: C. Corticoids
Explanation: The adrenal cortex secretes corticoids - glucocorticoids (sugar) and mineralocorticoids (salt/water) balance.
The hypothalamus releases hormones that direct the pituitary, which releases its own trophic hormone to a target gland; that gland's hormone output then feeds back (dashed lines) to suppress both the pituitary and hypothalamus once levels are sufficient - a self-correcting loop running the entire endocrine system.
