Question
8. EVEN THOUGH THE ANTERIOR PITUITARY IS CONSIDERED THE MASTER ENDOCRINE GLAND, WHAT PART OF THE BRAIN DETERMINES WHETHER OR NOT THE ANTERIOR PITUITARY RELEASES HORMONES OR NOT? IT DOES THRHOUGH MONITOR BLOOD CONCENTRATIONS AND BY PRODUCING RELEASING AND INHIBITING HORMONES INTO A PORTAL CIRCULATION
IT IS THE “REAL MASTER” OR “TRUE” BOSS ?
A) POSTERIOR PITUITARY B) CEREBRAL CORTEX GREY MATTER
C) PINEAL GLAND D) HYPOTHALAMUS
9. Which of these are amongst the classes of hormones made by the adrenal cortex?
A) mineralcorticoids like aldosterone
b) glucocorticoids like cortisol
c) sex hormones like minor amounts of estrogen and testosterone
d) all of the above
e) a and b only, the gonads produce all the sex hormones
10. What is true about the hormones calcitonin and PTH?
A) calcitonin is released from the thyroid when blood Ca++ is low; PTH is released from the parathyroid glands when blood Ca++ is high,
b) calcitonin is released from the parathyroid glands when blood Ca++ is low; PTH is released from the thyroid when blood Ca++ is high
c) calcitonin is released from the thyroid when blood Ca++ is high; PTH is released from the parathyroid glands when blood Ca++ is low
Matching 11, 12
11. Type II diabetes mellitus, NIDDM a) insulin deficeincy
12. Type I diabetes mellitus, IDDM b) insulin resistance
13. Obesity is more often linked to this type of diabetes, because it increases insulin resistance:
a) Type I, IDDM
b) Type II, NIDDM
14-18 Matching, pituitary hormones
14. FSH, LH a) stimulates faster and stronger uterine contractions
Milk release from breast glands
15. Growth hormone b) stimulates the thyroid to produce T3 and T4
16. TSH c) stimulates muscle, bone soft tissues
17.Oxytocin d) stimulates reabsorption of water in kidney tubules
18. ADH e) gonadotropins (stimulate ovaries and testes)
19. Choose the correct statement: a) the anterior pituitary is like the adrenal cortex because they both are nervous tissue; the posterior pituitary is like the adrenal medulla because they both are epithelial tissue modified for secretion
b) the anterior pituitary is like the adrenal cortex because they both are epithelial tissue modified for secretion; the posterior pituitary is like the adrenal medulla because they both are nervous tissue
c) the anterior pituitary is like the adrenal medulla because they both are epithelial tissue modified for secretion; the posterior pituitary is like the adrenal cortex because they both are nervous tissue
20. Growth hormone, promotes amino acid uptake, and increases blood glucose to help with growth by doing these things:
a) increasing fat (fatty acid) metabolism to spare blood glucose
b) increasing glycogen breakdown in the liver to glucose so it can be released into the blood
c) all of the above
Explanation / Answer
8. Hypothalamus
9. All of the above
10. C . Calcitonin is released from thyroid gland when Can is high. PTH is released when Ca is low.
11. Type II DM - NIDDM - Insulin Resistance
12. Type I DM - IDDM - insulin dependent diabetes mellitus - Insulin Deficiency
13. Type II DM, NIDDM
14. LSH, FSH - Gonadotropin
15. Growth hormone - Stimulate muscle and soft tissue
16. TSH - Stimulate thyroid
17. Oxytocin - Stimulate uterine contraction
18. ADH - stimulate reabsorption
19. B. Anterior pituitary is like adrenal cortex ----- posterior pituitary is like adrenal medulla
20. All of the above
