Hypothalamic Hormones that regulate the Anterior Pituitary

Thyrotropin-releasing hormone (TRH)

Promotes secretion of thyroid stimulating hormone (TSH) and prolactin (PRL)

Corticotropin-releasing hormone (CRH)

Gonadotropin-releasing hormone (GnRH)

Growth Hormone- releasing hormone (GHRH)

Promotes secretion of growth hormone (hGH)

Inhibitors

Prolactin- releasing hormone (PIH)

Somatostatin

Inhibits secretion of the growth hormone (GH) and thyroid- stimulating hormone (TSH)

Inhibits secretion of prolactin (PRL)

Promotes secretion of follicle- stimulating hormone (FSH) and luteinizing hormone (ZH)

Promotes secretion of adrenocorticotropic hormone (ACTH)

Follicle- stimulating hormone (FSH)

Luteinizing hormone (ZH)

Target Organ/ tissue FEMALE: ovaries

Targets Organ/ tissue MALE: testes

Target Organ/ tissue MALE: testes

Sperm production

Growth of ovarian follicles and secretion of estrogen

Targets Organ/ tissue FEMALE: ovaries

Testosterone secretion

Ovulation, maintenance of corpus luteum, prepares mammary glands, prepares uterus for implantation

Growth Hormone (GH)

Target Organ/tissue: Liver, Bone, Cartilage, Muscle, Fat

Wide spread tissue growth

Adrenocorticotropic hormone (ACTH)

Target Organ/ tissue: Adrenal Cortex

Growth of adrenal cortex, secretion of glucocorticoids (cortisol)

Thyroid stimulating hormone (TSH)

Prolactin (PRL)

Target Organ/ tissue: Thyroid Gland

Target Organ/ tissue: Mammary Hormone

Prolactin (PRL)

Growth hormone (GH)

Thyroid- stimulating hormone (TSH)

Target Organ/ tissue:Liver, Bone, Cartilage, Muscle, Fat

Target Organ/ tissue: Thyroid Gland

Target Organ/ tissue: Mammary Gland

Hormones secreted by the Anterior Pituitary Gland to various parts of the body

Wide spread growth

Growth of thyroid, secretion of thyroid hormone

Growth of thyroid, secretion of thyroid hormone

milk synthesis, Creation of milk

Milk Synthesis

Impulse sent from the Hypothalamus to the posterior Pituitary

Hormones secreted by the Posterior Pituitary Gland

Antidiuretic Hormone (ADH)

Target Organ: Kidneys

Oxytocin (OT)

Target Organs/ Tissue: Uterus, and Mammary Glands

Labor contractions, milk release: possibly involved in ejaculation, sperm transport, sexual affection, and mother- infant bonding

With excess production this will turn off the production of GnRH in the hypothalamus, and the pituitary

With excess production this will turn off the production of ACTH in the hypothalamus, and the pituitary

T3, T4

IGF: insulinlike growth factor
