Which gland secretes Growth Hormone?

The pituitary gland is responsible for secreting Growth Hormone (GH), also known as somatotropin. This hormone plays a critical role in stimulating growth, cell reproduction, and regeneration in humans and other animals. The secretion of GH is carefully regulated by hypothalamic hormones, particularly growth hormone-releasing hormone (GHRH) and somatostatin.

The anterior part of the pituitary gland, where GH is produced, receives signals from the hypothalamus to either promote or inhibit the release of growth hormone, depending on the body's needs at any given time. This regulation is crucial for the proper development during childhood and maintaining healthy metabolism in adults.

Understanding the function of the pituitary gland and its relationship with the hypothalamus is essential for grasping the overall endocrine system's functioning and how hormonal imbalances can lead to growth disorders.
