b. thyroid hormone inhibits the secretion of TSH-releasing hormone (TRH) from the hypothalamus.
c. TRH inhibits the secretion of thyroid hormone by the thyroid gland.
d. thyroid hormone stimulates the hypothalamus to secrete TRH.

- Figure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.arrow_forwardWhich of the following statements about steroid and non-steroid hormones is false?a. Non-steroid hormones typically act through second messengers such as cAMP.b. Non-steroid hormones are not lipid soluble and cannot enter the target cell.c. Steroid hormones act usually slower than non-steroid hormones.d. Cortisol and aldosterone are non-steroid hormones that are produced by the cortex of the adrenal glandarrow_forwardThyroid stimulating hormone (TSH).... a. secretion is stimulated by thyrotropin-releasing hormone (TRH). b. secretion is inhibited by triiodothyronine (T3). c. increases the rate of thyroid hormone secretion. d. has all of the above characteristics.arrow_forward
- Tumors that affect the pituitary can lead to decreases in some, but not all, hormones released by the pituitary. A patient with such a tumor exhibits fatigue, weight loss, and low blood sugar. This is probably due to lack of production of a. GH, which leads to loss of muscle mass. b. ACTH, which leads to loss of production of glucocorticoids. c. TSH, which leads to loss of production of thyroxin. d. ADH, which leads to excess urine production.arrow_forwardWhich of the following correctly describes the functions of the endocrine system? a. Transport of blood through the body and through the lungs b. Regulation of body functions through hormone secretion c. Regulation of body functions through nerve impulses d. Immunity and returning extra tissue fluid to the blood vesselsarrow_forwardChoose the statement that most accurately predicts the long-term effectof exposure to a substance that prevents the active transport of iodideby the thyroid gland.a.

- Growth hormone therapy has been widely used to help people with dwarfism and has helped certain individuals to become taller. Some recent studies have identified another hormone as potentially beneficial, which is given in conjunction with growth hormone. Given their general function, which hormone would supplement or enhance the effects of hGH? Select one: a. calcitonin b. cortisol c. inhibin d. parathyroidarrow_forwardhGH stimulates the liver to excrete growth factors. In combination with each other, hGH and growth factors affect many body processes.One role of hGH is to metabolize fats. Another hormone in the body that has a similar role to hGH and the gland that secretes that hormone are respectively: Select one: a. Hormone Gland Parathyroid hormone Thyroid gland b. Hormone Gland Thyroxine Thyroid gland c. Hormone Gland Parathyroid hormone Parathyroid gland d. Hormone Gland Thyroxine Parathyroid glandarrow_forwardThe condition hypothyroidism is characterized by a decrease in the synthesis and secretion of the chemical thyroid hormone from the thyroid gland, an organ in the neck that is part of the endocrine system. Which level of organization does not match this condition? A. The thyroid glad is regulated by others hormones from other glands in the body at an organ system level. B. The endocrine system works with the cardiovascular system to allow transporting the hormones throughout the body function at the organism level. C. At the tissue level group's of follicular cells that make the thyroid hormones form a spherical structure with a hollow interior called follicle. D. The plasma membrane of follicular cells that are found in the thyroid gland is made up of phospholipid bilayer at the tissue level.arrow_forward
