Endocrine Organs that have endocrine cells
Hypothalamus
Regulatory Hormones: secreted into blood to regulate secretion of most anterior pituitary hormones with 2 groups
Releasing Hormones (RH): stimulate production and secretion of specific anterior pituitary hormones.
Corticotropin-Releasing Hormone (CRH)
Target: Corticotropic cells in pars distills of anterior pituitary. Increases secretion of adrenocorticotropic hormone (ACTH)
Gonadotropin-Releasing Hormone (GnRH)
Targets Gonadotropic cells in pars distills of anterior pituitary. Increases secretion of follicle-stimulating hormones (FSH) and luteinizing hormone (LH).
Growth Hormone-Releasing Hormone (GHRH); Called Somatocrinin
Targets somatotropin cells in pars distills of anterior pituitary. Increases secretion of growth hormone (GH).
Prolactin-Releasing Hormone (PRH)
Targets Mammotropic cells in pars distills of anterior pituitary. Increases secretion of prolactin (PRL)
Thyropin-Releasing Hormone (TRH)
Targets Thyrotropic cells in pars distills of anterior pituitary. Increases secretion of thyroid-stimulating hormone (TSH)
Inhibiting Hormones (IH): Deter the production and secretion of specific anterior pituitary hormones.
Growth Hormone-Inhibiting Hormone (GHIH); Also Called Somatostatin
Targets somatotropin cells in pars distills of anterior pituitary. Decreases secretion of growth hormone (GH)
Prolactin-Inhibiting Hormone (PIH); Also Called Dopamine
Targets Mammotropic cells in pars distills of anterior pituitary. Decreases secretion of prolactin (PRL)
Pancreas
Glucagen
Target liver and adipose cells. Increases blood glucose levels, glycogen breakdown in liver cells, lipid breakdown in adipose cells.
Insulin
Targets liver and body cells. Decreases glucose levels in body fluids, glucose transport into target cells; promotes glycogen and lipid formation and storage.
Somatostatin
Target Alpha and beta cells of pancreatic islets. Slows release of insulin and glucagon to slow rate of nutrient absorption during digestion.
Pancreatic Polypeptide
Targets Delta cells of pancreatic islets. Suppresses somatostatin secretion from delta cells
Thymus
Thymopoietin and Thymosins
Act by stimulating and promoting the differentiation, growth, and maturation of T-lymphocytes
Testes
Androgens (primarily testosterone)
Stimulates male reproductive organ development, production of sperm
Inhibin
Inhibits secretion of follicle-stimulating hormone
Kidney
Calcitriol
Promotes calcium absorption in small intestine
Erythropoietin
Stimulates erythrocyte production and maturation
GI tracts
Various hormones related to digestion
Controls overall secretory activity and motility in GI tract
Ovaries
Estrogen
Stimulates development of female reproductive organs, follicle maturation; regulates menstrual cycle; stimulates growth of mammary glands.
Progesterone
Regulates menstrual cycle; stimulates growth of uterine lining; stimulates growth of mammary glands
Inhibin
Inhibits secretion of follicle-stimulating hormone
