Intolerance to heat, tachycardia, and weight loss<br>b. Oligomenorrhea, fatigue, and warm skin<br>c. Restlessness, increased appetite, and metrorrhagia<br>d. Constipation, decreased heat rate, and lethargy<br>The lower levels of thyroid hormone result in decreased energy metabolism, resulting<br>in constipation, bradycardia, and lethargy, thus eliminating the remaining options.<\/li>\n\n\n\n<li>Thyroid-stimulating hormone (TSH) is released to stimulate thyroid hormone (TH) and is<br>inhibited when plasma levels of TH are adequate. This is an example of:<br>a. Positive feedback<br>b. Neural regulation<br>c. Negative feedback<br>d. Physiologic regulation<br>Negative feedback. Feedback systems provide precise monitoring and control of the<br>cellular environment. Negative feedback occurs because the changing chemical, neural,<br>or endocrine response to a stimulus negates the initiating change that triggered the<br>release of the hormone. Thyrotropin-releasing hormone (TRH) from the hypothalamus<br>stimulates TSH secretion from the anterior pituitary. Secretion of TSH stimulates the<br>synthesis and secretion of THs. Increasing levels of T4 and triiodothyronine (T3) then<br>generate negative feedback on the pituitary and hypothalamus to inhibit TRH and TSH<br>synthesis.<\/li>\n\n\n\n<li>Lipid-soluble hormone receptors are located:<br>a. Inside the plasma membrane in the cytoplasm<br>b. On the outer surface of the plasma membrane<br>c. Inside the mitochondria<br>d. On the inner surface of the plasma membrane<br>Inside the plasma membrane in the cytoplasm. Lipid-soluble hormone receptors are<br>located inside the plasma membrane and easily diffuse across the plasma membrane to<br>bind to either cytosolic or nuclear receptors.<\/li>\n\n\n\n<li>The releasing hormones that are made in the hypothalamustravel to the anterior<br>pituitary via the:<br>a. Vessels of the zona fasciculata<br>b. Hypophysealstalk<br>c. Infundibular stem<br>d. Portal hypophyseal blood vessels<br>Portal hypophyseal blood vessels. Releasing and inhibitory hormones are synthesized in<br>the hypothalamus and are secreted into the portal blood vessels through which they<br>travel to the anterior pituitary hormones.<\/li>\n\n\n\n<li>Which mineral is needed for thyroid-stimulating hormone (TSH) to stimulate the<br>secretion of thyroid hormone (TH)?<\/li>\n<\/ol>\n\n\n\n<p>2<br>a. Iron<br>b. Iodide<br>c. Zinc<\/p>\n\n\n\n<p>3<br>d. Copper<br>Iodide. TSH, which is synthesized and stored in the anterior pituitary, stimulates<br>secretion of TH by activating intracellular processes, including the uptake of iodine<br>necessary for the synthesis of TH.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"6\">\n<li>What effect does hyperphosphatemia have on other electrolytes?<br>a. Increases serum calcium<br>b. Decreases serum magnesium<br>c. Decreases serum calcium<br>d. Increases serum magnesium<br>Decreases serum calcium. Hyperphosphatemia leadsto hypocalcemia. Remember that<br>phos and calcium are inversely related.<\/li>\n\n\n\n<li>Insulin transports which electrolyte in the cell?<br>a. Potassium<br>b. Sodium<br>c. Calcium<br>d. Phosphorus<br>Potassium. Insulin facilitatesthe intracellular transport of potassium, phosphate, and<br>magnesium.<\/li>\n\n\n\n<li>Which second messenger is stimulated by epinephrine binding to a \u03b2-adrenergic<br>receptor?<br>a. Calcium<br>b. Inositol triphosphate (IP3)<br>c. Diacylglycerol (DAG)<br>d. Cyclic adenosine monophosphate (cAMP)<br>Cyclic adenosine monophosphate (cAMP). Second-messenger molecules are the initial<br>link between the first signal (hormone) and the inside of the cell. For example, the<br>binding of epinephrine to a \u03b2 adrenergic\u2013receptor subtype activates (through a<br>stimulatory G protein) the enzyme, adenylyl cyclase. Adenylyl cyclase catalyzes the<br>conversion of adenosine triphosphate (ATP) to the second messenger, 3&#8242;, and 5&#8242;-cAMP.<\/li>\n\n\n\n<li>Regulation of the release of catecholamines from the adrenal medulla is an example of<br>which type of regulation?<br>a. Negative feedback<br>b. Neural<br>c. Positive feedback<br>d. Physiologic<br>Neural. The release of hormones occurs either in response to an alteration in the cellular<br>environment or in the process of maintaining a regulated level of certain hormones or certain<br>substances. Several different mechanisms, one of which is neural control (e.g., stress-induced<br>release of catecholamines from the adrenal medulla), regulate the release of hormones.<\/li>\n\n\n\n<li>Which hormone doesthe second messenger calcium (Ca++) bind to activate<br>phospholipase C through a G protein?<br>a. Angiotensin II<br>b. Estrogen<br>c. Thyroxine<\/li>\n<\/ol>\n\n\n\n<p>4<br>d. Testosterone<br>Angiotensin II. Ca++ is considered an important second messenger that facilitates the<br>binding of a hormone (e.g., norepinephrine, angiotensin II) to a surface receptor,<br>activating the enzyme phospholipase C through a G protein inside the plasma<br>membrane.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"11\">\n<li>The control of calcium in cells is important because it:<br>a. Is controlled by the calcium negative-feedback loop.<br>b. Is continuously synthesized.<br>c. Acts as a second messenger.<br>d. Carries lipid-soluble hormones in the bloodstream.<br>Acts as a second messenger. In addition to being an important ion that participates in a<br>multitude of cellular actions, Ca++ is considered an important second messenger.<\/li>\n\n\n\n<li>Where is antidiuretic hormone (ADH) synthesized, and where does it act?<br>a. Hypothalamus; renal tubular cells<br>b. Anterior pituitary; posterior pituitary<br>c. Renal tubules; renal collecting ducts<br>d. Posterior pituitary; loop of Henle<br>Hypothalamus; renal tubular cells. Once synthesized in the hypothalamus, ADH acts on<br>the vasopressin 2 (V2) receptors of the renal duct cells to increase their permeability.<\/li>\n\n\n\n<li>How does a faulty negative-feedback mechanism result in a hormonal imbalance?<br>a. Hormones are not synthesized in response to cellular and tissue activities.<br>b. Decreased hormonal secretion is a response to rising hormone levels.<br>c. Too little hormone production isinitiated.<br>d. Excessive hormone production results from a failure to turn of the system.<br>Excessive hormone production results from a failure to turn off the system. Negativefeedback systems are important in maintaining hormones within physiologic ranges. The<br>lack of negative-feedback inhibition on hormonal release often results in pathologic<br>conditions. Excessive hormone production, which is the result of the failure to turn of<br>the system, can cause various hormonal imbalances and related conditions.<\/li>\n\n\n\n<li>A deficiency of which chemical may result in hypothyroidism?<br>a.
