    1. 1. Science Notes: Ch. 16; The Endocrine System
    2. 2. Endocrine Differences from Nervous system The nervous system works by sending an action potential along an axon and then a chemical is released at the end of the nerve path. Acts quickly, shorter-term effect The Endocrine system works by an endocrine gland releasing a hormone directly into the blood: Acts slower: longer-lasting effect.
    3. 3. General FunctionsRegulation of metabolismRegulation of emotionsRegulation of growth & developmentRegulation of sexual reproduction
    4. 4. Some Specific FunctionsWater balance.Uterine contraction during birth.Milk release from breasts.Tissue maturation.Heart rate.Blood pressure.Blood glucose concentration.Immune cell production.Reproduction.
    5. 5. Glands of the Endocrine System Hypothalamus Pituitary Thymus Adrenal Testes & Ovaries Pancreas Parathyroid Thyroid Pineal body
    6. 6. Main Hormones & Their Functions Copy and memorize 6 of the following hormonesAntidiruretic hormone Regulates fluid & electrolyte balance in the kidney.Luteinizing hormone Stimulate release of estrogen and testosterone.Thymosin enhances the ability of the immune system.Cortisol Immune suppression & stress response.Testosterone, Estrogen, Progesterone Regulates reproductive processes.Insulin Regulates blood sugar levels.Parathyroid hormone Regulates blood levels of calcium in the blood.Thyroxine Regulation of metabolism.Melatonin Regulates the onset of puberty by acting on hypothalamus;regulates our biological clock.Click here for a detailed list of hormone actions on the Web
    7. 7. DefinitionsHormones--turn on, turn off, speed up, slow downthe activities of of different tissues and organs; Achemical messenger.The Brain & Nervous System--regulates if ahormone is released or not, when, & how much.Target Cell Receptor Proteins--allow hormones toact on certain organs but not others by the presenceor absence of these cells.
    8. 8. Glands to Know...Hypothalamus: This gland is the link between the nervous system and the endocrine system. Found in the brain. The hypothalamus receives nerve messages that produce hormones that control other adrenal glands.
    9. 9. Glands to Know...Pituitary; Also found in the brain. Communicates with hypothalamus to regulate many body activities. Releases more types of hormones than any other gland. Stimulates production of estrogen, sperm, stimulates growth, milk production, & maintains skin tone.
    10. 10. Negative FeedbackNegative feedback happens whenhormone production reaches a high leveland this triggers the adrenal system toproduce a second hormone which turns offproduction of the first hormone.
