Which part of the pituitary gland is responsible for the secretion of various hormones including growth hormone?

The anterior lobe of the pituitary gland is primarily responsible for the secretion of a variety of hormones, including growth hormone (GH). This lobe, also known as the adenohypophysis, plays a crucial role in regulating several physiological processes by releasing hormones directly into the bloodstream.

Growth hormone is vital for growth, cell repair, and metabolism. It stimulates growth in tissues and bones and influences the body’s ability to utilize fats and glucose for energy. The anterior lobe also secretes other hormones such as thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), and luteinizing hormone (LH), which all have significant roles in different bodily functions and endocrine regulation.

In contrast, the posterior lobe of the pituitary gland primarily stores and releases hormones that are produced in the hypothalamus, such as oxytocin and vasopressin (antidiuretic hormone). The intermediary lobe is less prominent in adults and is involved in pigment production in some species rather than hormone secretion relevant to human physiology. The term "hormonal lobe" is not a recognized part of the pituitary anatomy and does not relate to any specific function in the secretion of hormones.
