The pituitary gland, often referred to as the "master gland," plays a vital role in regulating various bodily functions by releasing hormones that influence growth, metabolism, and reproduction. It is located at the base of the brain and interacts closely with the hypothalamus to maintain homeostasis. The gland secretes hormones that control other endocrine glands, such as the thyroid and adrenals, and regulates processes like stress response and milk production in females. Proper functioning of the pituitary is essential for overall health and development.
