Question 5 0 / 0 pts The Anterior Pituitary 18. What major hormones are secreted from the anterior pituitary gland? 19. Fill in the chart, below with the purpose and target of each of the anterior pituitary hormones: *Note: All hormones in this module will need to be memorized for the exam. This is not an exhaustive list. Making a chart of all the hormones in the module to organize the information is a recommended way to study for the exam. Hormone Target Action GH TSH Gonadotropic hormones (FSH, LH) Your Answer: 18. GH, prolactin, MSh, TSH, ACTH, FSH, LH 19. Hormone Target Action GH TSH skeletal muscles, liver and bones thyroid gland cell growth, cell division, protein synthesis production of T3 and T4 FSH gonads follicle development/ estrogen production LH gonads ovulation, progesterone release, pregnancy maintenance 25. Explain the targets and opposing actions of calcitonin and PTH, using the chart below Hormone Target Action Calcitonin PTH Your Answer: 20. A goiter occurs when the thyroid gland enlarges due to lack of iodine in the diet 21. False 22. T3 and T4, calcitonin 23. False 24. PTH 25. Hormone Target Action lowers blood Calcitonin blood kidneys, bones, PTH intestines, blood calcium levels blood calcium increases/ phosphate decreases 20. When iodine is lacking in the diet, the thyroid gland enlarges, called a goiter. Goiters happen because of the relationship between the thyroid and the anterior pituitary. When there is a low level of thyroxin in the blood, the anterior pituitary continues to produce TSH. The thyroid responds by increasing in size (and producing a goiter). However, this size increase is ineffective because active thyroxin cannot be produced without iodine. 21. False 22. T3, T4, Calcitonin 23. False (Calcitonin lowers the level of calcium in the blood, depositing calcium into the bone) 24. PTH 25. *Note: All hormones in this module will need to be memorized for the exam. This is not an exhaustive list. Hormone Target Action DECREASE Blood Ca2+ Calcitonin Bone Cells Increase storage of Ca2+ in bone INCREASE Ca2+ in plasma PTH Bone Cells Decrease Ca2+ in bone Vitamin D activation 28. Fill in the action of cortisol by using the chart below: Hormone Target Action Cortisol Your Answer: 26. Epinephrine and norepinephrine 27. Glucocorticoids, mineralocorticoids 28. Hormone Target Action Cortisol liver, muscle, fat raise blood glucose levels, counteracts inflammation The Adrenal Glands 26. Epinephrine and norepinephrine directly into the bloodstream under conditions of stress. 27. The two major classes of hormones made by the adrenal cortex are glucocorticoids and mineralocorticoids. 28. *Note: All hormones in this module will need to be memorized for the exam. This is not an exhaustive list. Hormone Target Action Metabolism/stress management Cortisol (glucocorticoid) (controlled by ACTH) Most cells Hydrolysis of muscle protein-> amino acids to enter blood *Raises blood glucose level Reduces inflammation - Counteracts inflammatory response Question 9 0 / 0 pts The Pancreas 31. Endocrine tissue of the pancreas is called . 32. A person has high levels of blood glucose. Would the alpha or beta cells be stimulated to release what hormone? 33. Summarize the function of insulin. Your Answer: 31. Pancreatic islets of Langerhans 32. Insulin would be secreted by beta cells 33. Metabolize glucose by stimulating liver, fat and muscle cells, glycogen storage by the liver, builds up fat and protein storage and prevents them being utilized by the body for energy The Pancreas 31. Endocrine tissue, called the pancreatic islets (of Langerhans). 32. Beta cells would release insulin. 33. Generally, insulin promotes the storage of nutrients, so they are on hand in times of low blood glucose. 40. True or False: The thymus is most active during childhood. Your Answer: 36. Testosterone helps to develop sex organs of males and ensure functionality, helps with sperm maturation and causes the larynx and vocal chords to enlarge leading to voice changes at puberty. 27. FSH 38. Estrogen and progesterone 39. Progesterone 40 False - childhood The Gonads 36. It is essential for the normal development and functioning of the sex organs in males. It is also necessary for the maturation of sperm. Greatly increased testosterone secretion at the time of puberty stimulates the growth of the penis and the testes. Testosterone also brings about and maintains the secondary sex characteristics in males that develop at the time of puberty. Testosterone causes growth of a beard, body hair, and pubic hair. It prompts the larynx and the vocal cords to enlarge, causing the voice to change. It is responsible for the muscular strength of males. Testosterone causes oil and sweat glands in the skin to secrete; therefore, it is largely responsible for acne and body odor. Testosterone is largely responsible for sex drive. 37. FSH 38. Estrogen and progesterone 39. Progesterone 40. True Quiz Score: 0 out of 0
