The name of the master gland in the human body is the pituitary gland. The pituitary gland is a small, pea-sized gland located at the base of the brain, and it plays a crucial role in regulating various bodily functions by secreting hormones that act on other endocrine glands. The pituitary gland is often referred to as the “master gland” because it controls the activity of other endocrine glands throughout the body. It is divided into two main parts: the anterior pituitary and the posterior pituitary. The anterior pituitary secretes hormones that regulate growth, metabolism, reproduction, and stress response, while the posterior pituitary secretes hormones that control water balance and milk production.
