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 Chapter 9 Concept Map Review Endocrine system Secondary messenger system Endocrine gland stimuli hormones glands chemistry mechanisms Chemistry of hormones Amino acid based Proteins, peptides, and amines steroid cholesterol Sex hormones and adrenaline prostaglandin lipids Endocrine gland stimuli Hormonal humoral Hormone stimulates Endocrine glands Changes blood level of ions Hypothalamus to anterior pituitary to target glands PTH and calcium neural Nerves stimulate hormone release Endocrine glands pineal hypothalamus pituitary thyroid parathyroid thymus adrenal pancreas ovary testis Pineal Gland melatonin controls sleep cycles Grape sized Fits in turk’s saddle Pituitary Gland Anterior Master gland Posterior Glandular tissue Growth hormone Prolactin neural tissue bones and muscles mammary glands Follicle-stimulating & Luteinizing Thyrotropic Adrenocorticotropic gonads thyroid adrenal gland Posterior Pituitary Oxytocin Antidiuretic hormone Stimulates contractions Stimulates milk ejection Stops postpartum bleeding Induces labor Increase blood pressure Stops urine production Prolactin (PRL) Protein based Pro – for, lact -milk Stimulates milk production Unknown function in males Growth Hormone (GH) Builds protein General metabolic Breaks down fats Maintains blood sugar homeostasis Hyposecretion causes dwarfism Hypersecretion causes gigantism Hypothalamus Gland Controls pituitary Thyroid Gland At base of Adam’s apple Thyroid hormone calcitonin Body’s major metabolic hormone Thyroxine (T4) Triiodothyronine (T3) Antagonist to Parathyroid hormone iodine Thymus Gland Thymosin Matures the T cells Pancreas islets alpha cells beta cells glucagon insulin Gets glucose into blood = hyperglycemic Gets glucose out of blood = hypoglycemic Parathyroid Gland Parathymone (PTH) Regulates calcium in blood If calcium levels too low = uncontrollable spasms (tetany) Adrenal Gland cortex glandular corticosteroids mineralocorticoids glucocorticoids sex hormones neural medulla catecholamines Epinephrine and norepinephrine aldosterone cortisone, cortisol Androgens, estrogens Ovary Estrogen Produced by Graafian follicles Progesterone Produced by Corpus luteum Testis Androgens Testosterone Produced by interstitial cells
