Under the influence of the hypothalamus, which gland regulates growth and controls other endocrine glands?

• A. Pituitary Gland
• B. Thyroid Gland
• C. Pancreas
• D. Adrenal Glands

Answer: (A)

The pituitary gland acts as the command center of the endocrine system. Under the influence of the hypothalamus, it releases hormones that directly regulate growth and also control other endocrine glands. The anterior part of the pituitary secretes growth hormone to drive development and body growth, and it sends tropic hormones (like TSH, ACTH, FSH, and LH) that tell the thyroid, adrenal glands, and gonads how active to be. Because of this central role in both promoting growth and coordinating other glands, the pituitary best fits the description. The thyroid, pancreas, and adrenal glands are important targets of pituitary hormones, but they don’t regulate growth or oversee the whole endocrine system in the way the pituitary does.
