Chapter 9 Concept Map Review
Endocrine system Secondary messenger system Endocrine gland
hormones chemistry mechanisms
Amino acid based steroid Proteins, peptides, and amines cholesterol Sex hormones and adrenaline prostaglandin lipids
Hormonal Hormone stimulates Endocrine glands Hypothalamus to anterior pituitary to target glands humoral Changes blood level of ions PTH and calcium neural Nerves stimulate hormone release
thyroid
melatonin controls sleep cycles
Grape sized
Fits in turk’s saddle Anterior Master gland Glandular tissue
neural tissue
bones and muscles
mammary glands Follicle-stimulating & Luteinizing Thyrotropic Adrenocorticotropic
Oxytocin Antidiuretic hormone Stimulates contractions Stimulates milk ejection Stops postpartum bleeding Induces labor Increase blood pressure Stops urine production
Protein based Pro – for, lact -milk Stimulates milk production Unknown function in males
Builds protein General metabolic Breaks down fats Maintains blood sugar homeostasis Hyposecretion causes dwarfism Hypersecretion causes gigantism
Controls pituitary
At base of Adam’s apple Thyroid hormone Body’s major metabolic hormone Thyroxine (T 4 ) iodine Triiodothyronine (T 3 ) calcitonin Antagonist to Parathyroid hormone
Thymosin Matures the T cells
islets alpha cells glucagon beta cells insulin Gets glucose into blood = hyperglycemic Gets glucose out of blood = hypoglycemic
Parathymone (PTH) Regulates calcium in blood If calcium levels too low = uncontrollable spasms (tetany)
cortex neural medulla glandular catecholamines corticosteroids mineralocorticoids glucocorticoids sex hormones Epinephrine and norepinephrine aldosterone cortisone, cortisol Androgens, estrogens
Estrogen Produced by Graafian follicles
Progesterone Produced by Corpus luteum
Androgens Testosterone Produced by interstitial cells
