Question 26 A new class of drug has been developed for patients with hyperglycemia type 2 diabetes; it works by acting as an agonist for the GLP-1 receptor, which reduces blood glucose levels. How does this new drug reduce the concentration of blood glucose? O A. Decreasing renal reabsorption of glucose OB. Long-loop negative feedback of ACTH OC. Increasing insulin release OD. Decreasing glucagon release OE. Inhibiting cortisol synthesis

Question 24 Which of the following is an effect of epinephrine? OA. Enhanced pain sensation B. Slowed heart rate OC. Increased GLUT4 cell surface expression in skeletal muscle D. Increased blood flow to the Gl E. Increase liver gluconeogenesis

Question 9 When would IGF-1 concentration in the blood stream be at its highest? O A. Immediately after a meal OB. In the absence of binding protein OC. When growth hormone concentration is at its lowest OD. During times of increased stress O E. At the peak of the pubertal growth spurt

Question 15 Which of the following is a consequence of glucocorticoid treatment for an extended period? O A. Reduced response to glucagon O B. Reduced response to ACTH C. Reduced IGF-1 synthesis O D. Inability to secret thyroid hormone O E. Hypoglycemia (low blood glucose)

Question 35 Estrogens are found at lower levels in adult males than females, however, they are important in males for which of the following? O A. Sebum production OB. Sperm production O C. Muscle protein catabolism O D. Adipose lipid catabolism O E. As a dihydrotestosterone prohormone 1

QUESTION 9 Match each hormone in the left column with its FUNCTION Testosterone luteinizing hormone (LH) Inhibin gonadotropin releasing hormone (GnRH) progestins (ex: progesterone) follicle stimulating hormone (FSH) Estrogens A. stimulates growth of endometrium B. negatively feeds back to inhibit secretion of FSH C. stimulates the release of FSH and LH from the anterior pituitary gland D. in males it stimulates sperm production in the testes; in females it stimulates the growth of an ovarian follicle, the secretion of estrogen, and the secretion of inhibin. E. stimulates male sex drive, protein synthesis, bone and muscle growth; establishes and maintains male secondary sexual characteristics; maintains male accessory glands and organs F. in males it stimulates cell of testes to produce testosterone; in females it stimulates completion of meiosis, induces ovulation, triggers development of the corpus luteum and promotes the secretion of progestins by the corpus luteum G. increases…

Question 37 Which of these is NOT a function of endocrine systems? O Glucose regulation Acid-base balance Muscle movement OSleep-wake cycle Sexual development

QUESTION 39 Treatment of Diabetes Insulin administration is a primary course of treatment for which type of diabetes? а. type 2 b. prediabetes c. gestational d. type 1

Question 22 Congenital adrenal hyperplasia (CAH) are a group of heritable disorders associated with a deficiency in cortisol synthesis. The most common cause of CAH is a mutation in the adrenal 21-a-hydroxylase cytochrome P450 that converts progesterone to 17-hydroxyprogesterone. One of the serious complications is a salt wasting syndrome which results in large serum sodium losses. What effects on hormone levels would be expected? OA. ACTH is elevated and aldosterone is reduced OB. ACTH is reduced and aldosterone levels remain unchanged OC. Both ACTH and aldosterone levels are unchanged OD. ACTH is elevated and aldosterone is unchanged OE. ACTH is reduced and aldosterone is elevated
