Which human endocrine gland is often referred to as the master gland because its tropic hormones stimulate and control the secretory activity of several other endocrine glands throughout the body?

💡 Solution & Explanation

The pituitary gland secretes multiple tropic hormones such as thyroid-stimulating hormone, adrenocorticotropic hormone, and gonadotropins that regulate the thyroid, adrenal cortex, and gonads, earning it the title of master gland, although its own secretion is controlled by the hypothalamus. The thyroid regulates metabolic rate, adrenals manage stress responses, and the pancreas controls blood glucose homeostasis via insulin and glucagon. Endocrine signaling relies on chemical messengers transported in the bloodstream.
