Target Function Regulated by Secreted

Growth Hormone Stimulates growth of Releasing Hormone Human growth , muscle, cartilage, body cells, protein (GHRH) and (hGH) synthesis Hormone Inhibiting Hormone (GHIH)

Thyrotropin Releasing Hormone (TRH - -stimulating Stimulates the release Anterior Pituitary Thyroid stimulated by low T3 hormone (TSH) of thyroid and T4 and low BMR) and GHIH

F: oocyte development Follicle-stimulating Anterior Pituitary /Testes & secretion / Releasing Hormone hormone (FSH) M: sperm production (GnRH)

F: estrogen and secretion Gonadotropin Anterior Pituitary Ovaries/Testes & timing of ovulation / Releasing Hormone (LH) M: (GnRH) production

Prolactin Releasing Hormone (PRH) and Anterior Pituitary (PRL) Mammary gland Promotes milk secretion Prolactin Inhibiting Hormone (PIH, )

Stimulates secretion of Adrenocorticotropic Corticotropin Releasing Anterior Pituitary Adrenal Cortex by adrenal hormone (ACTH) Hormone (CRH) cortex

Stimulates uterine Uterus/ Mammary Uterine growth and (OT) contractions and milk glands suckling "letdown" Conserves water by: Decreases urine Dehydration; blood Antidiuretic hormone Posterior Pituitary //Arterioles volume; decreases pressure; blood loss; (ADH) perspiration; constricts alcohol arterioles

Thyroid hormones (T3 Thyroid Multiple Tissues Increases TSH and T4)

Lowers blood Thyroid (CT) Bone/Kidney Blood calcium levels

Parathyroid hormone Increases blood Parathyroid Bone/Kidney Blood calcium (PTH) calcium levels

Conserves water by: Dehydration; Na+ Increases blood sodium Adrenal Cortex Kidney deficiency; blood loss; levels and water high blood K+ retention

Increases protein breakdown; provides ACTH; ; low Adrenal Cortex Cortisol Multiple Tissues resistance to stress; blood cortisol depresses immune system

Source of estrogen; Male and Female male and female Adrenal Cortex Androgens ACTH reproductive organs secondary sex characteristics

Increase HR and BP; increase blood flow to Sympathetic response Epinephrine and Adrenal Medulla Nervous system skeletal muscle, liver, to stress and exercise; and ; increase "fight-or-flight" blood glucose Increases blood (Alpha cells) Multiple Tissues Blood glucose glucose

Decreases blood Pancreas (Beta cells) Multiple Tissues Blood glucose glucose

Regulates female reproduction cycle; Female reproductive prepare mammary Ovaries Estrogen FSH and LH system glands for lactation; develps female 2nd-ary sex characteristics

Maintains pregnancy; Estrogen and Female reproductive LH and development of Ovaries helps regulate female Progesterone system corpus luteum reproductive cycle

Male reproductive Regulates sperm Testes Testosterone LH system formation

Pineal /Skin Sets biological clock Darkness

Maturation of T cells (a Presence of immature Thymus form of white blood T cells in thymus cells)
