Textbook Question
Chapter 34, Problem 1CT
Women who have been blind since birth almost never have breast cancer. A high level of one specific hormone is though to contribute to their low cancer rate. Which hormone is it and why are levels of this hormone unusually high in the blind?

Students have asked these similar questions
Hormones are signaling molecules that can alter cellular activity and gene expression. Hormones also have diverse chemical structures. How does the chemical nature of different classes of hormones influence how/where it interacts with target cells?
In hypothyroidism, the thyroid gland does not produce enough T3 or T4. As a result, target cells create more receptors. What is this an example of?
Hypothyroidism is a condition in which the thyroid gland fails to
produce adequate amounts crucial hormones. In the early stages,
persons suffering from this condition may be asymptomatic. However,
chronic hypothyroidism may show signs of paleness. Please explain the
physiological reasons for this symptomatology.

- Describe how hormone receptors can play a role in affecting the size of the responses of tissues to hormones.arrow_forwardWomen who are completely blind tend to undergo puberty at an earlier age than sighted women. They also are less likely to have breast cancer. By one hypothesis, blindness encourages early puberty and discourages breast cancer by its effect on melatonin secretion. Based on this information, would you expect the average melatonin level in blind women to be higher or lower than that of sighted women? Explain your answer.arrow_forwardWhich of the following best explains how hormone antagonists work? Multiple Choice By flooding the cancerous cells with hormones By blocking actions of hormones that the cancer cells need to function By competing with uracil or cytarabine and metabolizing the nutrients required for hormone production By inhibiting folic acid, which is essential for blood cell and hormone productionarrow_forward
- Thompson Medical Company manufactures and sells Aspercreme, a topical analgesic. Aspercreme is a pain reliever that contains no aspirin. Thompson’s advertisements strongly suggest that Aspercreme is related to aspirin, however, by claiming that it provides “the strong relief of aspirin right where you hurt.” Is Thompson’s advertisement for Aspercreme false and misleading? Explain.arrow_forwardWhich of the following observations can be explained by the properties of hormone receptors? a) A certain tissue can react to more than one hormone b) A certain hormone affects only a specific tissue, not all tissues c) Some tissues react very quickly to a certain hormone, other tissues take many hours to react to the same hormonearrow_forwardMany functions in the body are controlled by hormones – chemical signals that are secreted by one organ or tissue, but have effects in multiple areas. Calcium can enter the body from what we eat and drink. It circulates through blood and is used by many organs, so it’s level is carefully regulated. The amount of calcium in the blood is maintained at a relatively constant level by two hormones; for our purposes, we’ll just call them hormone A and hormone B. Hormone A is secreted by the parathyroid gland and it functions to increase blood calcium levels. Hormone B is secreted by parafollicular cells (C cells) in the thyroid gland and it functions to decrease blood calcium levels. Calvin, a teenage boy, begins eating ChocoRite™ Calcium Bites, a very tasty calcium supplement. He likes them so much that he ends up eating a whole package one afternoon. 1.Where does hormone B come from? A)From the calcium regulatory cells B)From the parathyroid gland C)From calcium supplements,…arrow_forward
- Melatonin is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Evaluate each statement below and select the statement that best describes the pathway. Select one: a. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to stop producing melatonin, signalling the body to go to sleep. b. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to increase the production of melatonin, signalling the body to go to sleep. c. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to stop producing melatonin, signalling the body to wake up. d. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to increase the production of melatonin, signalling the body to wake up.arrow_forwardIn your opinion, what is the significance of having the right cell receptors for a specific hormone? Provide an example to support your answer.arrow_forwardA physician examines a patient who reports that he has experienced excessive sweating, irritability, and feverish episodes. Assay of hormones in blood reveal that thyroid hormone levels are abnormally high, and TSH levels are low. An RAIU (radioactive iodine uptake scan) reveals a hot spot on the thyroid, indicating a localized region of intense iodine uptake. What do you predict that this patient’s diagnosis will be? How would you attempt to treat such a condition?arrow_forward

Being well- intentioned but ignorant, you start injecting him with growth hormone as he sleeps each night. You. think this is a clever strategy, but after a time you notice that he hasn’t grown an inch. Instead, his jaw and forehead seem to have gotten disproportionately large and his hands and feet are swollen. Explain why the growth hormone didn’t make Bud grow taller and why it had the effect it did. What disease state do these changes mimic?arrow_forward
