Hormones Produced by the Hypothalamus, Posterior Pituitary Lobe, and Anterior Pituitary Lobe

Corticotropin-releasing hormone (CRH): Stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH), which in turn triggers the adrenal glands to produce cortisol (stress hormone).

Hypothalamus

Thyrotropin-releasing hormone (TRH): Signals the pituitary gland to release thyroid-stimulating hormone (TSH), which controls thyroid hormone production.

Hypothalamus

Gonadotropin-releasing hormone (GnRH): Stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), essential for reproduction.

Hypothalamus

Growth hormone-releasing hormone (GHRH): Promotes the release of growth hormone from the pituitary gland.

Hypothalamus

Somatostatin: Inhibits the release of growth hormone and other hormones like TSH.

Hypothalamus

Growth hormone (GH): Stimulates cell growth and division, impacting bone and muscle development.

Posterior pituitary lobe

Thyroid-stimulating hormone (TSH): Controls thyroid hormone production by stimulating the thyroid gland.

Posterior pituitary lobe

Adrenocorticotropic hormone (ACTH): Stimulates the adrenal glands to release cortisol.

Posterior pituitary lobe

Follicle-stimulating hormone (FSH): In females, stimulates follicle development in the ovaries; in males, stimulates sperm production.

Posterior pituitary lobe

Luteinizing hormone (LH): Triggers ovulation in females and testosterone production in males.

Posterior pituitary lobe

Prolactin (PRL): Milk synthesis

Posterior pituitary lobe

Oxytocin: Involved in childbirth contractions, milk ejection during lactation, and social bonding.

Anterior pituitary lobe

Antidiuretic hormone (ADH): Regulates water balance by controlling the reabsorption of water in the kidneys.
