NR 507 ENDOCRINE SYSTEM EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS 100% PASS (A+ CERTIFIED)

1. The only way for a hormone to work is through the blood stream Correct Answer False. The endocrine cell can also secrete hormones that target cells directly close it. When this occurs, this type of secretion is known as paracrine signaling. 2. Lipid-derived hormones cross the cell membrane and bind to receptors in the cell's cytoplasm Correct Answer True. This statement is true. Lipid-derived hormones cross the cell membrane and bind to receptors in the cell's cytoplasm. 3. The anterior lobe of the pituitary produces its own hormones Correct Answer True. This statement is true. The anterior lobe of the pituitary produces its own hormones 4. To be considered a lipid hormone, it must be bound to a protein and it must bind to receptors inside the cell membrane Correct Answer False. It must be bound to a protein and it bind to receptors on the cell membrane rather than inside the cell membrane. 5. The pineal gland is responsible for regulating the sleep-wake cycle Correct Answer True. 6. The posterior lobe of the pituitary produces its own hormones Correct Answer False. The posterior pituitary receives its hormones (oxytocin and ADH) from the hypothalamus. The anterior pituitary produces its own hormones. 7.

Type 2 DM Correct Answer Usually 40 years of age Associated with hyperosmolar nonketotic coma Symptoms: weakness, weight loss, infections Results from genetic susceptibility (polygenic) combined with environmental determinants and other risk factors Inherited defects in beta-cell mass and function combined with peripheral tissue insulin resistance
