The pituitary gland is the master gland because it secretes hormones that regulate the activity of other endocrine glands throughout the body. Its anterior part releases hormones such as thyroid-stimulating hormone, adrenocorticotropic hormone, luteinizing hormone, follicle-stimulating hormone, growth hormone, and prolactin, which stimulate the thyroid, adrenal cortex, gonads, and tissues involved in growth and metabolism. The hypothalamus controls the pituitary by sending releasing and inhibiting signals, coordinating when these hormones are released. The posterior pituitary releases oxytocin and vasopressin under hypothalamic control, but the key coordinating role still rests with the pituitary. The pineal gland mainly regulates sleep with melatonin, and the cerebellum is a brain region for movement coordination, not endocrine function. So, the pituitary gland best fits the description of the master gland.
