Endocrine regulation · USMLE Step 1

Which of the following is the most common mechanism by which hormone secretion is regulated in the endocrine system?

  1. Positive feedback from the target gland
  2. Negative feedback from the target gland
  3. Autocrine stimulation within the same gland
  4. Neural conduction along endocrine tissues
Show answer and explanation

Correct answer: Negative feedback from the target gland

Negative feedback from the target gland is the predominant mechanism by which hormone secretion is regulated: when target-gland hormone levels rise sufficiently, they inhibit further release from the hypothalamus and/or pituitary, maintaining homeostasis.
