  1. Endocrine System Tristan Simon Jake Amanda

  2. Overview • The endocrine system is a radio. It is slower, but it gets out to more people. The chemical messages get to more cells. • Endocrine- secretes hormones in to blood stream and extracellular fluid • Exocrine-secretes substance directly at the target (Not important yet)

  3. Endocrine Glands • Pineal Gland • Hypothalamus • Pituitary • Thyroid/Parathyroid • Thymus • Adrenal Glands • Pancreas • Gonads (Ovaries and Testes)

  4. pineal and hypothalamus • Pineal- releases melatonin which helps to regulate the biological clock • Hypothalamus- regulates pituitary gland. It makes the hormones that are stored in the pituitary gland

  5. pituitary and thyroid/parathyroid • Pituitary- Produces hormones that regulate many other endocrine glands. • Thyroid/Parathyroid- The thyroid regulates metabolism. The parathyroid regulates the amount of sodium in the blood.

  6. thymus and adrenal • Thymus- During childhood, the thymus stimulates T-cell development • Adrenal- stimulates the production of epinephrine and norepinephrine to aid the body in fight, flight, or, fright situations.

  7. Pancreas • Pancreas-it produces insulin and glucagon.

  8. Gonads (and strife) Ovaries- produce estrogen and progesterone (in females). Responsible for secondary sexual development. Testes- produce testosterone (in males). Responsible for sperm production and secondary sexual development.

  9. How the Hormones Work • Most hormones work by binding to receptors on the target cells. • Steroid hormones can enter a cell and alter DNA sequences. • Non-Steroid hormones CAN’T enter a cell, so they have to bind to receptors and use a secondary messenger. • Hormones are secreted into extracellular fluid, or directly into the blood stream.

  10. Questions 1. What are glands? (define exocrine and endocrine) A. Nostrils B. Muscles C. openings that secrete hormones D. Ear Canals 2. What is a Hormone? Give an Example. A. chemical message B. a hotdog C. farts D. Pancreatic juice 3. Where is the Hypothalamus? A. In the abdomen B. in the legs C. in the head D. the nose 4. How are steroid different from non-steroid hormones? A. one is red and the other is blue B. one is round and the other is square C. one is fat and the other is skinny D. one can enter a cell and the other can’t.

  11. More Questions • 5. What hormone/gland controls the fight, fright, or flight? A. the adrenal gland/epinephrine B. The pineal gland C. thegonads D. the thyroid glands 6. Insulin is produced where? A. Pancreas B. Hypothalamus C. Kidneys D. Ovaries 7. Where is sperm produced? A. Ovaries B. Gonads C. Testes D. Hypothalamus 8. What is a target cell? A. destination for a hormone B. a cell with a target on its back C. where cells go to shop D. a chief cell

On the membrane • 16. The exocrine glands secrete substances to where? • The bloodstream B. The urine C. The target zone D. The oil in hair • 17. The ovaries produce these two hormones…. • Progesterone/Estrogen B. Progesterone/Testosterone C. Estrogen/Testosterone D. ADH/Testosterone

  14. More Questions • 18. The thyroid gland produces what? • A. Thyroxine B. Canterflumul C. Menengitis D. Methane • 19. The pineal gland produces what? • Melatonin B. Flagnarg C. La Mov D.
