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. 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






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






3. Testes: male characteristics; spermatogenesis






4. Hypothalamus -> Anterior Pituitary: modifies activities






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






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






7. Atrial natriuretic factor (ANF) & Aldosterone






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






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






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






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






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






13. Kidney -> Bone Marrow: increases RBC synthesis






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






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






16. Parathyroid hormone and Calcitonin






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






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






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






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






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






22. Adrenal Medulla: sympathetic stress response (rapid)






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






24. Ovaries / Placenta: Female characteristics - endometrial growth






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






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






27. Insulin and Glucagon






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






29. Posterior Pituitary -> Kidney: water retention






30. Anterior Pituitary -> Mammary Gland: milk production






31. Oxytocin and Prolactin






32. 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
