Which gland is commonly called the master gland?

• A. Thyroid Gland
• B. Pituitary Gland
• C. Adrenal Gland
• D. Hypothalamus

Answer: (B)

The pituitary gland is commonly called the master gland because it releases hormones that regulate the activity of multiple other endocrine glands throughout the body. Located at the base of the brain, it acts as a central coordinator, receiving input from the hypothalamus and then secreting a range of hormones that set the activity levels of other glands. The anterior part of the pituitary releases several key hormones: TSH stimulates the thyroid, ACTH stimulates the adrenal cortex, LH and FSH regulate the gonads, growth hormone influences growth and metabolism, and prolactin promotes milk production. The posterior part releases oxytocin and vasopressin, which are produced in the hypothalamus but stored and released from the pituitary. Through these hormones, the pituitary oversees growth, metabolism, reproduction, and stress responses, giving it that classic label as the master regulator of the endocrine system. The hypothalamus, meanwhile, governs the pituitary by sending releasing or inhibiting signals, but it is the pituitary that exerts the broad coordinating control over other glands.
