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






2. 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






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






4. Ovaries / Placenta: Female characteristics - endometrial growth






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






6. Oxytocin and Prolactin






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






8. Insulin and Glucagon






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






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






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






12. SIGMA Cells of The Islets of Langerhans In The Pancreas: inhibits many digestive processes






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






14. Posterior Pituitary -> Kidney: water retention






15. Anterior Pituitary -> Mammary Gland: milk production






16. Adrenal Medulla: sympathetic stress response (rapid)






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






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






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






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






21. Parathyroid hormone and Calcitonin






22. Testes: male characteristics; spermatogenesis






23. 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






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






25. Hypothalamus -> Anterior Pituitary: modifies activities






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






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






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






29. Atrial natriuretic factor (ANF) & Aldosterone






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






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






32. Kidney -> Bone Marrow: increases RBC synthesis
