Chapter 18.4, Problem 15BYGO
Summary Introduction
To determine:
The similarities present between the thyroid gland, adrenal gland, and pituitary gland with respect to embryonic development and explain the comparison.
Introduction:
The exocrine glands produce the hormones are distributed by the vascular system to the body. A human fetus is entirely dependent on the hormones. The pituitary gland is the major gland that regulates the functioning of other glands. These glands coordinate with the whole endocrine system.

- Name the connection between the hypothalamus and the posterior pituitary gland. What does it consist of? Explain the mechanism of release of the posterior pituitary hormones into the systemic circulation. Describe the difference between gigantism and acromegaly.arrow_forwardSex hormone secretion is governed by a negative feedback loop to the hypothalamus and pituitary, similar to that for thyroid hormone or cortisol. Because of this, a veterinarian can use a blood test to find out whether a female dog has been neutered. Dogs who still have their ovaries have a lower blood level of luteinizing hormone (LH) than dogs who have been neutered. Explain why removing a dog’s ovaries would result in an elevated level of LH.arrow_forwardIn Graves' disease, the body attacks the thyroid gland tissue and causes it to overproduce thyroid hormones, resulting in elevated blood levels of T3 and T4. Which of the following statements would be TRUE? Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would release more TSH. Since blood levels of thyroid hormones are elevated, the hypothalamus would release more TRH and the Anterior Pituitary Gland would then stop releasing TSH. Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would not release TSH. Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TSH and the Anterior Pituitary Gland would not release TRH.arrow_forward
- If the pituitary is so important, and if Eric is not getting replacements of hormones the pituitary makes (except for adh), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect Is it because the hypotalamus secretes it to the blood stream directly? May I have an explanation? I'm trying to understand so that I can answer this question properlyarrow_forwardList several conditions that can stimulate the production ofadrenal medullary hormones.

- Another general principle of physiology is that structure is a determinant of—and has coevolved with—function. The structure of the thyroid gland is very unlike other endocrine glands.

- Julie is five months pregnant and is not receiving any prenatal care. She has a poor diet consisting mostly of fast food. She drinks no milk, preferring instead carbonated sodas. How would this situation affect Julie’s level of parathyroid hormone? What organ systems could be impacted the most? Considering her diet, what other conditions is Julie at risk of developing? What are two benefits of having a portal system connect the median eminence of the hypothalamus and the anterior pituitary?arrow_forwardA tumor in the pituitary gland can cause a woman to produce milk even when she is not pregnant. In which lobe of the pituitary would such a tumor be located, and what hormone would it affect?arrow_forwardWhich of the following statements is incorrect? (a) The anterior lobe of the pituitary gland secretes seven different hormones. (b) The infundibulum connects the pituitary gland to the hypothalamus. (c) Portal veins connect the anterior lobe of the pituitary gland to the hypothalamus. (d) The pars distalis is the largest part of the anterior lobe of the pituitary gland.arrow_forward
