The thymus and parathyroid glands are not on the mini torso model, where would they be located if they were? 6. Describe hypothalamus function. 7. List the 6 major hormones of the anterior pituitary (adenohypophysis) and their function. 8. List the two hormones secreted from the posterior pituitary (neurohypophysis) and give their function. 9. Identify Thyroid Gland secretions and functions 10. In the thyroid gland the __________________ cells produce thyroid hormone (T3 and T4) and the extrafollicular cells produce _________________. 11. Identify parathyroid secretions and functions. 12. The adrenals have several endocrine secretions and functions. Identify and describe the hormones of the adrenal cortex and the adrenal medula. 13. The pancreas functions in both the digestive and endocrine systems. Identify its endocrine secretions and their functions. 14. The brain communicates with the pituitary gland through the________________________. 15. What hormone from the posterior pituitary gland increases water permeability of the collecting ducts of the kidney’s nephrons when you are dehydrated, thereby reducing urine output and further water loss? 16. There are two endocrine hormones that are produced in the pancreas which regulate blood glucose levels. ________________________causes an increase in blood glucose and ________________________causes a decrease in blood glucose. 17. Of the hormones produced by the thyroid gland, the ________________________hormones regulate metabolism and ________________________helps regulate blood calcium levels. 18. ________________________increases blood calcium levels, it is antagonistic to ________________________. 19. Claudia suffers from the symptoms of hypothyroidism (typically caused by too little thyroid hormone), but she has normal thyroid hormone levels. What could be going wrong with Claudia? 20. A 50 year-old man presents with enlargement of left anterior neck. He has noted increased appetite over past month with no weight gain, and more frequent bowel movements over the same period. Lab results show an increase in free thyroxine (T4), elevated calcium, and low TSH. Which endocrine disease do you suspect he has? 21. Joe was born with a mutation in his insulin receptor causing him to suffer from the symptoms of diabetes. Will giving Joe insulin help his condition? Why or why not? 22. Generically, without mentioning any specific hormone or disease, describe what can go wrong with hormone signaling that will result in the effective loss of hormone function. 23. The following graph indicates the observed blood glucose changes in two individuals after eating a meal. The black line, drawn with diamond symbols, represents a person with diabetes mellitus. The pink line, drawn with square symbols, represents a person without diabetes. Explain the physiological reason for the differences between the two.
