Tropic hormone - Citizendia

Tropic hormones are hormones that regulate the activity of various other endocrine glands. Hormones (from Greek ὁρμή - "impetus" are chemicals released by cells that affect cells in other parts of the body Endocrine glands are Glands that secrete their product ( Hormones, directly into the blood rather than through a duct

One example is the thyroid-stimulating hormone (TSH) (produced by the anterior pituitary) and stimulates the thyroid gland to secrete thyroid hormones. Thyroid-stimulating hormone (also known as TSH or thyrotropin) is a Peptide hormone synthesized and secreted by Thyrotrope cells in the The thyroid is one of the largest Endocrine glands in the body The thyroid hormones, Thyroxine ( T4) and Triiodothyronine ( T3) are Tyrosine -based Hormones produced It is the thyroid hormones that actually causes metabolic changes in the human body, in this case to increase metabolic rate and body temperature.

Tropic hormones made and secreted by the anterior pituitary include:

Thyroid-stimulating hormone (TSH) - stimulates the thyroid gland. Thyroid-stimulating hormone (also known as TSH or thyrotropin) is a Peptide hormone synthesized and secreted by Thyrotrope cells in the
Adrenocorticotropic hormone (ACTH or corticotropin) - stimulates the adrenal cortex. Adrenocorticotropic hormone ( ACTH or corticotropin) is a Polypeptide Hormone produced and secreted by the Pituitary gland Adrenocorticotropic hormone ( ACTH or corticotropin) is a Polypeptide Hormone produced and secreted by the Pituitary gland
Luteinizing hormone (LH) - stimulates the release of steroid hormones in the ovary and testes. Luteinizing hormone ( LH, also known as lutropin) is a Hormone produced by the Anterior pituitary gland.
Follicle-stimulating hormone (FSH) - stimulates the maturation of eggs and sperm. Follicle-stimulating hormone ( FSH) is a Hormone synthesized and secreted by Gonadotropes in the Anterior pituitary gland.

The release of tropic hormones is controlled by a class of hypothalamic hormones called releasing hormones, produced in the hypothalamus. The hypothalamus links the Nervous system to the Endocrine system via the Pituitary gland (hypophysis For example, luteinizing hormone releasing hormone (LHRH) from the hypothalamus stimulates the release of LH from the anterior pituitary. Gonadotropin-releasing hormone ( GNRH) also known as Luteinizing-hormone releasing hormone ( LHRH) is a tropic Peptide Hormone Thus, while the anterior pituitary controls hormone release in most somatic endocrine glands, the pituitary itself is controlled by the hypothalamus.
