Which gland releases nine hormones and regulates many of the other endocrine glands?

The pituitary gland, often referred to as the "master gland," releases nine hormones and plays a crucial role in regulating many of the other endocrine glands in the body. It controls functions such as growth, metabolism, and reproduction by signaling other glands, including the thyroid and adrenal glands. The pituitary gland is divided into the anterior and posterior lobes, each responsible for different hormones and functions.
