1. Endocrine and Integumentary Systems SESSION 39

2. Objectives  Describe the components of the integumentary system  Describe the locations and major hormones associated with the essential glands of the endocrine system  Analyze the relationship between the endocrine system and nervous system

4. Hormones: Mechanism of Action  Target cells  Receptors

5. Endocrine Glands  Pituitary Gland  “Master Gland”  Growth Hormone, prolactin, adrenocorticotropic hormone, thyroid- stimulating hormone, luteinizing hormone, follicle-stimulating hormone, oxytocin, antidiuretic hormone  Pineal Gland  Melatonin  Thyroid  Hormones involved in metabolism  Thymus  Hormones released during puberty, mainly involved in immunity

6. Endocrine Glands  Pancreas  Insulin, blood sugar control  Adrenal  Adrenaline (epinephrine), blood sugar control  Testes  Testosterone  Ovaries  Estrogen and progesterone

7. Locations 1. Pineal 2. Pituitary 3. Thyroid 4. Thymus 5. Adrenals 6. Pancreas (Shown Wrong!) 7. Ovary 8. Teste

8. Research Hormone Functions  5 minutes – prepare for a brief presentation. What does it do? Where is it found? What is an interesting piece of information about this hormone?  Assign each group member a number  I will randomly select someone in your group to present your hormone  Make sure you’re ready! 1. growth hormone 2. prolactin 3. adrenocorticotropic hormone 4. thyroid-stimulating hormone 5. luteinizing hormone 6. follicle-stimulating hormone 7. oxytocin 8. antidiuretic hormone 9. adrenaline 10. testosterone 11. estrogen 12. progesterone

9. Hormone Functions 1. growth hormone – somatotropin, increases glucose & fatty acids, ant. pituitary 2. Prolactin – pituitary, milk production, pancreatic dev. >300 functions 3. adrenocorticotropic hormone – ant. Pituitary, stress inflammation or immune, 4. thyroid-stimulating hormone – pituitary, feedback to supply thyroid hormones, maintain metabolism 5. luteinizing hormone – gonadotropin (stimulates gonads), ant. Pituitary, 6. follicle-stimulating hormone – ant. Pituitary, growth & reproductive processes, tests for infertility 7. Oxytocin – hypothalamus, “bonding”, positive feedback for labor, destroyed in GI tract 8. antidiuretic hormone – prevents urination, descreases fluid release, electrolyte regulation, pituitary (vasopressin similar) 9. Adrenaline – (epinephrine), released by sympathetic NS, increases HR, vasoconstrictor, bronchodilator 10. Testosterone – steroid, testes or ovaries, anabolic effects, androgenic effects 11. Estrogen – ovaries, liver, adrenal glands, breasts, increases fat storage, reproductive regulation, bone formation 12. progesterone

10. Endocrine & Nervous Systems

11. Objectives  Describe the components of the integumentary system  Describe the locations and major hormones associated with the essential glands of the endocrine system  Analyze the relationship between the endocrine system and nervous system

12. Wednesday  After tag test (11:15), lab will be open for checking answers and review  Lecture will be optional and informal for review only  Please email me topics that you’d like to go over Wednesday  Please bring questions that you have  I will stop answering emails Sunday evening at 8pm  If I don’t see you Wednesday, see you Monday at 11:30am for the Final Exam!
