Endocrine System-Part 1 Chap 25 (choices may be used once only or more than once) chemical structure antagonistic cholesterol steroid kidney epithelial, nervous or both receptors oxytocin cyclic AMP paracrine parathyroid PG, thromboxanes non-steroid permissive negative increasing no. of receptors amine, peptide, protein, glycoprotein PGE 1. The chemical messenger of the endocrine system are called: 2. The nervous system functions with much speed than the endocrine system. 3. What kind of tissues make up endocrine glands: 4. Which of the two major types of glands is ductless: 5. Hormones bind specific 6. Up-regulation increases sensitivity of target cells by 7. Unused hormones circulating in the blood are excreted by the: 8. The most widely used method of hormone classification is: 9. Nonsteroid hormones include the following 4 groups: 10·The precursor of all steroid hormones is: 11. Which group of hormones is transported in blood with the help of protein carriers: 12. Hormones that have target cells within the same tissue are called 13. List two groups of tissue hormones: 14. A tissue hormone involved in fever development 15. A second messenger is involved in mechanism/action 16. A well known second messenger is: 17. Hormones bind to fixed receptors in plasma membrane inmechanism/action 18. Receptor is mobile in cytoplasm or nucleus in mechanism. 19. Regulation of gene occurs in mechanism. One hormone produces the opposite effect of another hormone. 21. One hormone acts as a primer allowing the second hormone to have its full effect on a target cell. 22. One of the few hormones that functions on a positive-feedback loop is: 23. Insulin secretion is controlled by a -feedback mechanism. 24. Name an endocrine gland that responds to neural stimuli 25. Name an endocrine gland that responds to humoral stimuli 26. Name an endocrine gland that responds to hormonal stimuli 20.Explanation / Answer
1. Hormones As they may be amines or proteins or steroid or glycoproteins which induce specific functions in target tissue.
2. greater. As neurons pass signals using action potential developed in axolemma.
3. Epithelial or nervous or both.
4. Endocrine As they release and transport their hormones into and through blood stream.
