Hormones The Endocrine System

The Pituitary Anterior produces & releases hormones All second- messenger Four tropic hormones Posterior stores & releases hormones produced by hypothalamus

Growth Hormone (GH) Anterior pituitary Dwarfism Gigantism Acromegaly

ADH Triggered by hypothalamus Stored in posterior pituitary (Vasopressin)

Thyroid Hormones Regulated by hormones from hypothalamus & pituitary (TSH) T3 & T4 control rate glucose is metabolized to create body heat & energy Goiter Graves disease

Thyroid Hormones

Adrenal Glands

Negative Feedback

Hormones in Future Units Anterior pituitary – prolactin, FSH, LH Posterior pituitary (from hypothalamus) – oxytocin Adrenal cortex – estrogen, testosterone Ovaries – estrogen, progesterone Testes – androgens Placenta – hCG Thymus - thymosin Also leptin, prostaglandins, and erythropoetin
