  3. Endocrine 1 - 10 Points QUESTION: • What are two features of the endocrine system? ANSWER: • Ductless glands • Coordinates with nervous system • Slow responses

  4. Endocrine 1 – 20 Points QUESTION: • This type of hormone circulates in the blood bound to plasma proteins? ANSWER: • Steroid hormones

  5. Endocrine 1 – 30 Points QUESTION: • Which hormone causes blood glucose to increase? Name the two ways it does this. ANSWER: • Glucagon • Gluconeogenesis • Glycogenolysis

  6. Endocrine 1 – 40 Points QUESTION: • What causes diabetes mellitus? What are three signs of diabetes? ANSWER: • Hyposecretion of insulin or hypoactivity of insulin • Polydipsia, polyphagia, polyuria

  7. Endocrine 1 – 50 Points QUESTION: • Describe the production of thyroid hormone? ANSWER: • Iodine moves from the blood through the follicle cell into the lumen • Thyroglobulin is synthesized in the golgi apparatus, moves to lumen • Tyrosines and iodine combine to make T1 and T2 • These combine to make T3 and T4 • Form lysosome in follicle cell, this removes excess colloid • T3 and T4 exocytosed into blood
