MCAT Hormones

Subjects : mcat, science
Instructions:
  • Answer 32 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. SIGMA Cells of The Islets of Langerhans In The Pancreas: inhibits many digestive processes






2. Anterior Pituitary -> Mammary Gland: milk production






3. Atrial natriuretic factor (ANF) & Aldosterone






4. Thyroid: in the child it is necessary for physical and mental development; in the adult - it increases metabolic rate and temperature






5. Anterior Pituitary -> Ovary / Testes: follicle development or spermatogenesis






6. Adrenal Cortex: not normally important - but an adrenal tumor can overproduce these - causing masculinization or feminization.






7. ALPHA Cells of The Islets of Langerhans In The Pancreas: secreted at low blood [glucose] and results in an increase in blood [glucose] and decrease in glycogen and fat storage






8. Glucagon (polypeptide derivative) - Epinepherine (amino acid derivative) - Cortisol (steroid / glucocorticoid)






9. Oxytocin and Prolactin






10. Oxytocin - Prolactin - Progesterone - Estrogen - LH - FSH






11. Anterior Pituitary -> Thyroid: increases synthesis and release of thyroid hormone (tropic)






12. Posterior Pituitary -> Breast & Uterus: milk letdown and uteral contractions






13. Insulin and Glucagon






14. Adrenal Cortex: results in a longer - term stress response; increased blood [glucose]; increased protein catabolism; decreased inflammation and immunity; many other






15. Anterior Pituitary: increases bone and muscle growth - increases cell turnover rate






16. Testes: male characteristics; spermatogenesis






17. Thymus: is involved in T- cell development during childhood.






18. Hypothalamus -> Anterior Pituitary: modifies activities






19. Kidney -> Bone Marrow: increases RBC synthesis






20. Parathyroid hormone and Calcitonin






21. ParaThyroids -> Bone - Kidney - Small Intestine: raises serum [Ca2+]






22. Posterior Pituitary -> Kidney: water retention






23. Anterior Pituitary -> Adrenal Gland: increases growth and secretory activity of adrenal cortex






24. Glucagon (alpha) & Insulin (beta) & Somatostatin (sigma)






25. Adrenal Medulla: sympathetic stress response (rapid)






26. Anterior Pituitary -> Ovary/ Testes: ovulation or testosterone synthesis






27. Heart -> Kidney: increases urination to decrease blood pressure






28. BETA Cells of The Islets of Langerhans In The Pancreas: decreases blood [glucose]; increases glycogen and fat storage; it is activated at high blood [glucose] and is absent or ineffective in diabetes melitus






29. Adrenal Medulla -> Kidney: increased Na+ reabsorption to increase blood pressure






30. Ovaries / Placenta: Female characteristics - endometrial growth






31. Ovaries / Placenta: leads to endometrial secretion - pregnancy






32. Thyroid C Cells -> Bone - Kidney - Small Intestine: lowers serum [Ca2+]
