What is referred to as the "master" gland of the endocrine system?

The pituitary gland is often referred to as the "master" gland of the endocrine system because it plays a crucial role in regulating various hormonal functions of other glands. Located at the base of the brain, the pituitary gland produces and releases hormones that influence growth, metabolism, and the functioning of other endocrine glands, including the thyroid and adrenal glands.

It controls the thyroid gland, which regulates metabolism, by secreting thyroid-stimulating hormone (TSH). Additionally, it produces adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol. The wide-ranging impact of the pituitary gland as a central coordinator of hormonal activity solidifies its title as the master gland, as it orchestrates the hormonal signals that maintain body homeostasis and regulate key biological processes.
