M6: Exam- Requires Respondus LockDown Question 1 5 / 5 pts Explain two reasons why a woman with low levels of LH would not be able to become pregnant. Your Answer: 1- LH provides on the ovary to cause ovulation to occur. 2-Progesterone is very important for maintenance pf pregnancy. LH makes progesterone release. And it helps to make easy potential fertilization of the egg and pregnancy. (1) LH acts on the ovary to cause ovulation to occur. (2) LH causes progesterone release to facilitate potential fertilization of the egg and pregnancy. Progesterone is a key hormone for the maintenance of pregnancy. Question 2 5 / 5 pts Would you expect a female to have testosterone in their bloodstream? Explain why or why not. Your Answer: Yes. Female and male bodies both produce all the sex hormones. But ratios are different. The adrenal glands mostly responsible for produce opposite hormone that the ovaries would not. (1) Yes. Both male and female bodies produce “all” the sex hormones. However, the ratios are different. (2) The adrenal glands are largely responsible for producing this “opposite” hormone that the ovaries would not. Question 3 10 / 10 pts Label the endocrine glands (A-D) A: ______________ B: ______________ C: ______________ D: ______________ Your Answer: A: Thyroid B: Adrenal gland C: Kidney D: Pancreas A: Thyroid gland B: Adrenal gland C: Kidney D: Pancreas Question 4 10 / 10 pts Explain the concept of negative feedback and how it helps to maintain homeostasis. GH -Growth hormone Question 9 2 / 2 pts The posterior pituitary stores these two hormones: ADH and LH Correct! ADH and Oxytocin LH and FSH TSH and Prolactin Question 10 2.5 / 2.5 pts List the hormone(s) that best describes the statement below: I lower the level of calcium in the blood by depositing calcium into bone. Your Answer: Calcitonin. Calcitonin Question 11 2.5 / 2.5 pts List the hormone(s) that best describes the statement below: I am secreted by the pituitary and stimulate the gonads. Your Answer: FSH or LH (Gonadotropic hormones) FSH LH Gonadotropic hormones Question 12 2.5 / 2.5 pts List the hormone(s) that best describes the statement below: I am secreted by the beta cells of the pancreas. Your Answer: Insulin. Insulin Question 13 2.5 / 2.5 pts List the hormone(s) that best describes the statement below: I cause blood glucose to rise and breakdown stored nutrients. Your Answer: Glucagon. Glucagon Question 14 10 / 10 pts Answer the following question. Explain in detail how PTH and calcitonin work to maintain calcium balance. Your Answer: Parathyroid hormone works in concert with another hormone, calcitonin, that is produced by the thyroid to maintain blood calcium levels. PTH increases the calcium level in the blood. Thus, eventually the calcium in bone is decrease. But calcitonin is get lower the levels of calcium in the blood and it deposit calcium into the bone. They work oppeses. Basically, parathyroid hormone acts to increase blood calcium levels, while calcitonin acts to decrease blood calcium levels. Calcitonin: produced by the thyroid glands, deposits calcium into bone. Calcitonin opposes the action of PTH. When the blood calcium level reaches the appropriate level through all these means, the parathyroid glands stop producing PTH through negative feedback. PTH: produced by the parathyroid glands increase the amount of calcium in the blood. (Any one of the following explanations of PTH is acceptable) PTH stimulates the increased absorption of calcium from the intestines. PTH retains calcium through excreting phosphate at the kidneys. In the bones, PTH promotes the activity of osteoclasts to demineralize of the bone, increasing the amount of calcium in the blood. Question 15 0 / 2 pts Which hormone/s are involved in milk production? A. Thyroxin B. Oxytocin Correct Answer C. Prolactin You Answered D. B &C E. A&B Question 16 2 / 2 pts Which gland decreases in size with age? Thyroid However this increase in size is not effective, because active thyroxin can not be produced without iodine. 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, but this increase in size is ineffective because active thyroxin cannot be produced without iodine. Question 21 10 / 10 pts Matching each of the following conditions with the one best explanation (1-5): 1. Jet Lag A. Underproduction of GH as a child 2. Pituitary dwarf B. Overproduction of GH as a child 3. Acromegaly C. Overproduction of GH as an adult 4. Inflammation D. Results if PTH is not produced in response to low blood calcium 5. Tetany E. Cortisol helps to counteract this condition F. Melatonin production is produced according to body’s normal rhythm G. Lack of erythropoietin to act on the bone marrow H. Results if calcitonin is not produced in response to low blood calcium Correct! 1. Jet Lag Correct! 2. Pituitary dwarf Correct! 3. Acromegaly F. Melatonin production is produced according to body’s normal rhythm A. Underproduction of GH as a child Correct! 4. Inflammation Correct! 5. Tetany Other Incorrect Match Options:  B. Overproduction of GH as a child  H. Results if calcitonin is not produced in response to low blood calcium  G. Lack of erythropoietin to act on the bone marrow Question 22 2 / 2 pts In addition to the endocrine system, the pancreas is also part of which system? Excretory Nervous Circulatory Correct! Digestive Question 23 2 / 2 pts What hormone/s are produced by the adrenal medulla? C. Overproduction of GH as an adult E. Cortisol helps to counteract this condition D.
