The gland in the brain that is commonly referred to as the 'master gland' is the Pituitary gland. This small, pea-sized gland plays a crucial role in regulating various bodily functions by releasing hormones that control other glands in the endocrine system. Specifically, the pituitary gland secretes hormones that influence growth, metabolism, and sexual maturation. It impacts the thyroid gland, adrenal glands, and reproductive organs, among others, thus earning its designation as the 'master gland.' While the hypothalamus also plays an essential role in hormone regulation and homeostasis, the pituitary directly influences many bodily functions and hormonal outputs, solidifying its title in the context of being the regulatory center of the endocrine system.
