Adrenal Gland (p 525) Steroid hormones and their glands Other endocrine glands Compare Endocrine and Nervous systems

Developed by John Gallagher MS DVM

Adrenal (or Suprarenal) Gland

Adrenal Medulla modified sympathetic ganglion produces epinephrine and norepinephrine (parallels sympathetic division of ANS) n Adrenalinreg = adrenaline =

epinephrine n Neuroendocrine gland

Adrenal (or Suprarenal) Gland

Adrenal cortex n Corticosteroid

Steroid Hormones

All steroid hormones have a common chemical backbone derived from cholesterol Slight differences in branches decide the hormonersquos activity Lipid soluble Estrogen progesterone testosterone cortisol aldosterone calcitriol vitamin D

More Steroids

Sex Steroids n Female estrogen and progesterone n Male testosterone AKA anabolic

steroids Corticosteroids n From adrenal cortex n Cortisol (antiinflammatory)

Mineralocorticoids Aldosterone (preserves Na+) Calcitriol (active form of Vit D from kidneys absorbs Ca2+)

Anabolic Steroids

Fluoxymesterone brand name Halotestin Oxandrolone brand name Anavar Methandrostenolone brand name Dianabol Methyltestosterone brand name Metandren Oreton Methyl Nandrolone Decanoate brand name Deca-Durabolin Testosterone Propionate brand name Testex Testosterone Cypionate brand name Depo-Testosterone Stanozolol brand name Winstrol Testolactone brand name Teslac Dromostanolone Propionate brand name Drolban Nandrolone Phenpropionate brand name Durabolin Testosterone Enanthate brand name Delatestryl Ethylestrenol brand name Maxibolin Danazol brand name Danocrine Calusterone brand name Methosarb Testosterone Undecanoate Testosterone Cyclohexanecarboxylate Dihydrotestosterone Methenolone Acetate brand name Primobolan Testosterone-trans-4-n-butylcyclohexyl-carboxylate code name 20Aet-1

Pineal gland

Part of epithalamus Secretes melatonin n Derivative of serotonin n Regulates circadian Rhythms

(sleep cycle) n Inhibits hypothalamic releasing

factors Decreases repro function

Pancreas

Endocrine AND exocrine functions n Exocrine portion covered in Digestive System

Pancreatic islets or Islets of Langerhans (1 x 106 islets) n α cells glucagon (uarr blood sugar levels by stimulating liver to convert

glycogen to glucose) n β cells insulin (51 aa) (darr blood sugar levels by causing the cells to

take up glucose for use by the mitochondria) n δ (delta) cells somatostatin n F cells pancreatic polypeptide

Pancreatic Islet

Diabetes

Diabetes mellitus n Type 1

AKA IDDM juvenile onset Deficiency of insulin

n Type 2 (90 of DM) AKA NIDDM adult onset Decreased production of insulin ANDOR some sort of deficiency in receptors (insulin resistance) Related to obesity lack of exercise age Often controlled by diet oral hypoglycemics

Diabetes insipidus n Deficiency of ADH n Much less common

Thymus Gland

Inside thoracic cavity immediately posterior to sternum above the heart Most active in infancy and childhood - Largest just before puberty then atrophies Thymosin - enhances T-lymphocyte production and competence (important for immune system development)

Testes

Secrete testosterone into the bloodstream n From interstitial cells n Stimulates sperm production

(along with FSH) n Secondary sex

characteristics Inhibin (balances FSH) n From sustentacular (Sertoli)

cells Other minor secretions

Ovaries

Estrogenmdashby ovarian follicles in response to FSH Progesteronemdashby the corpus luteum (pl corpora lutea) in response to LH Inhibinmdashdecreases estrogen prodrsquon

Other Endocrine Structures p 529

Heart Atrial Natriuretic Peptide Brain Brain Natriuretic Peptide GI Tract Enteroendocrine cells regulate digestive processes Stomach Ghrelin (not in book) Adipose Leptin antagonist to ghrelin

Other Endocrine Structures p 529

Kidneys n Renin converts angiotensin to angiotensin I

Regulates BP n Erythropoietin Stimulates production of RBCs

Skin Precursor to Vitamin D Placenta pregnancy n hCG n Progesterone n HPL ndash Human placental lactogen (increases [glucose]) n Relaxin ndash relaxes pubic symphysis and cervix

Other Hormones

Prostaglandins (not in the book) n Approx 12 types similar structure widely different

functions n Derived from FA n Produced in cell membranes in most cells

Does not fit some definitions of ldquohormonerdquo n Very short half-life (tfrac12) n Involved in inflammatory response

NSAIDs are prostaglandin inhibitors Gastrinmdashproduce gastric HCl Human Chorionic Gonadotropin (HCG) Endorphins Others yet to be discovered

Pancreas

Endocrine AND exocrine functions n Exocrine portion covered in Digestive System

Pancreatic islets or Islets of Langerhans (1 x 106 islets) n α cells glucagon (uarr blood sugar levels by stimulating liver to convert

glycogen to glucose) n β cells insulin (51 aa) (darr blood sugar levels by causing the cells to

take up glucose for use by the mitochondria) n δ (delta) cells somatostatin n F cells pancreatic polypeptide

Pancreatic Islet

Diabetes

Diabetes mellitus n Type 1

AKA IDDM juvenile onset Deficiency of insulin

n Type 2 (90 of DM) AKA NIDDM adult onset Decreased production of insulin ANDOR some sort of deficiency in receptors (insulin resistance) Related to obesity lack of exercise age Often controlled by diet oral hypoglycemics

Diabetes insipidus n Deficiency of ADH n Much less common

Thymus Gland

Inside thoracic cavity immediately posterior to sternum above the heart Most active in infancy and childhood - Largest just before puberty then atrophies Thymosin - enhances T-lymphocyte production and competence (important for immune system development)

Testes

Secrete testosterone into the bloodstream n From interstitial cells n Stimulates sperm production

(along with FSH) n Secondary sex

characteristics Inhibin (balances FSH) n From sustentacular (Sertoli)

cells Other minor secretions

Ovaries

Estrogenmdashby ovarian follicles in response to FSH Progesteronemdashby the corpus luteum (pl corpora lutea) in response to LH Inhibinmdashdecreases estrogen prodrsquon
