Which gland is often referred to as the "master gland" of the body?

  1. Thyroid gland

  2. Pituitary gland

  3. Adrenal gland

  4. Pancreas

The correct answer is: Pituitary gland

The pituitary gland is often referred to as the "master gland" of the body because it plays a crucial role in regulating various hormonal functions and controls many other endocrine glands. Located at the base of the brain, the pituitary gland produces and secretes hormones such as growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone, which influence growth, metabolism, and stress responses. Its regulatory functions extend to the thyroid gland, adrenal glands, and reproductive organs, coordinating the overall hormonal balance in the body. This pivotal role in the endocrine system solidifies its nickname as the "master gland," highlighting its significance in maintaining homeostasis within the body.
