Which gland is commonly referred to as the master gland?

The pituitary gland is considered the master gland because it releases hormones that regulate the function of nearly all other endocrine glands. It sends signals like TSH to stimulate the thyroid, ACTH to stimulate the adrenal cortex, and gonadotropins to control the ovaries and testes, along with growth hormone and prolactin for growth, metabolism, and reproduction. The hypothalamus helps control the pituitary with releasing and inhibiting hormones, but it doesn’t directly govern all other glands; its influence is mediated through the pituitary. So, the gland that’s commonly called the master gland is the pituitary.
