Endocrine system Secondary messenger system Endocrine gland

stimuli

glands

hormones chemistry mechanisms

Chemistry of hormones

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

Endocrine gland stimuli

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

Endocrine glands

pineal

hypothalamus

pituitary

thyroid

parathyroid

thymus

adrenal

pancreas

ovary

testis

Pineal Gland

melatonin controls sleep cycles

Grape sized

Pituitary Gland

Fits in turk’s saddle Anterior Master gland Glandular tissue

Posterior

neural tissue

Growth hormone

bones and muscles

Prolactin

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 Body’s major metabolic hormone Thyroxine (T 4 ) iodine Triiodothyronine (T 3 ) calcitonin Antagonist to Parathyroid hormone

Thymus Gland

Thymosin Matures the T cells

Pancreas

islets alpha cells glucagon beta cells 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 neural medulla glandular catecholamines corticosteroids mineralocorticoids glucocorticoids sex hormones Epinephrine and norepinephrine aldosterone cortisone, cortisol Androgens, estrogens

Estrogen Produced by Graafian follicles

Ovary

Progesterone Produced by Corpus luteum

Testis

Androgens Testosterone Produced by interstitial cells
