Which brain structure controls the pituitary gland by releasing hormones?

• A. Amygdala
• B. Hypothalamus
• C. Pituitary Gland
• D. Thalamus

Answer: (B)

The hypothalamus is the brain structure that regulates the pituitary by releasing hormones. It sits just above the pituitary and sends releasing and inhibiting hormones into the pituitary’s blood supply, especially to the anterior lobe. This hypothalamic-hypophyseal portal system tells the anterior pituitary when to release hormones like ACTH, TSH, growth hormone, and others, and when to hold back. It also produces neurohormones (oxytocin and vasopressin) that travel down to the posterior pituitary to be released into the bloodstream. In short, the hypothalamus acts as the control center that directs pituitary activity through hormone release. The amygdala and thalamus aren’t responsible for this hormonal control, and the pituitary gland is the target, not the controller.
