Endocrine and Integumentary Systems SESSION 39
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
Hormones: Mechanism of Action Target cells Receptors
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
Endocrine Glands Pancreas Insulin, blood sugar control Adrenal Adrenaline (epinephrine), blood sugar control Testes Testosterone Ovaries Estrogen and progesterone
Locations 1. Pineal 2. Pituitary 3. Thyroid 4. Thymus 5. Adrenals 6. Pancreas (Shown Wrong!) 7. Ovary 8. Teste
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
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
Endocrine & Nervous Systems
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
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 me topics that you’d like to go over Wednesday Please bring questions that you have I will stop answering s Sunday evening at 8pm If I don’t see you Wednesday, see you Monday at 11:30am for the Final Exam!
