1 Bell Work 3-10 Write today’s assignments in your planner.
Write down and answer the following: What is the hormone that is present in the urine during pregnancy that is detectable by home pregnancy tests? HCG

2 Chapter 9 Concept Map Review
Endocrine system Secondary messenger system Endocrine gland hormones stimuli glands chemistry mechanisms

3 Chemistry of hormones steroid prostaglandin lipids cholesterol
Amino acid based steroid prostaglandin Proteins, peptides, and amines lipids cholesterol Sex hormones and adrenaline

4 Endocrine gland stimuli
Hormonal humoral neural Changes blood level of ions Nerves stimulate hormone release Hormone stimulates Endocrine glands Hypothalamus to anterior pituitary to target glands PTH and calcium

5 Endocrine glands ovary pineal testis hypothalamus pituitary thyroid parathyroid thymus adrenal pancreas

6 Pineal Gland melatonin controls sleep cycles

7 Follicle-stimulating & Luteinizing
Fits in turk’s saddle Grape sized Pituitary Gland Master gland Posterior Anterior Glandular tissue neural tissue bones and muscles Growth hormone mammary glands Prolactin Follicle-stimulating & Luteinizing gonads Thyrotropic thyroid Adrenocorticotropic adrenal gland

8 Stimulates contractions
Posterior Pituitary Oxytocin Antidiuretic hormone Increase blood pressure Stimulates contractions Stimulates milk ejection Stops postpartum bleeding Stops urine production Induces labor

9 Stimulates milk production Unknown function in males
Prolactin (PRL) Protein based Pro – for, lact -milk Stimulates milk production Unknown function in males

10 Maintains blood sugar homeostasis
Growth Hormone (GH) Builds protein General metabolic Breaks down fats Maintains blood sugar homeostasis Hyposecretion causes dwarfism Hypersecretion causes gigantism

11 Hypothalamus Gland Controls pituitary

12 Thyroid Gland At base of Adam’s apple Thyroid hormone calcitonin Body’s major metabolic hormone Antagonist to Parathyroid hormone Thyroxine (T4) iodine Triiodothyronine (T3)

13 Thymus Gland Thymosin Matures the T cells

14 Pancreas islets alpha cells beta cells insulin glucagon Gets glucose into blood = hyperglycemic Gets glucose out of blood = hypoglycemic

15 Regulates calcium in blood
Parathyroid Gland Parathymone (PTH) Regulates calcium in blood If calcium levels too low = uncontrollable spasms (tetany)

16 Epinephrine and norepinephrine
Adrenal Gland medulla cortex neural catecholamines glandular Epinephrine and norepinephrine corticosteroids mineralocorticoids aldosterone glucocorticoids cortisone, cortisol sex hormones Androgens, estrogens

17 Ovary Progesterone Estrogen Produced by Graafian follicles Produced by Corpus luteum

18 Testis Androgens Testosterone Produced by interstitial cells
