MCAT Human Body

Subjects : mcat, science
Instructions:
  • Answer 50 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. In the direction of the cranium






2. A canal






3. Secretion; protection






4. Fingerlike projections of plasma membranes; mainly located at luminal surfaces of absorptive cells (brush border of proximal convoluted tubules and striated border of intestinal epithelium)






5. Striated - involuntary






6. In the direction of the head end of the body






7. Limits and protects the body as a whole; prevents excess loss of water; functions in regulating body temperature






8. Away from the center of the body; toward the outside






9. In the direction of the head; nearer the head






10. Functions in the exchange of gases (oxygen and carbon dioxide)






11. A smooth - rounded articular surface






12. Thinner than collagen but similar size to elastic; arranged in an intermeshing network (reticulum) which supports the organ; inelastic






13. Perpetuates the living organism by the production of sex cells (gametes) and future offspring






14. At cell surface; Microvilli - cilia - flagella - stereocilia






15. Male urethra; conjunctiva






16. A cavity in a bone (maxillary sinus); a venous blood channel in the cranium (cavernous sinus); or a cavity in a viscus - such as the pharynx (piriform sinus)






17. Free surface






18. A shallow depression






19. Has free surface (apical) and an attached surface (basal)






20. In the direction of the tail end of the body or away from the head end






21. Retractile fibers; thinner than collagen fibers;






22. Toward the center of the body; toward the inside






23. Toward the front of the body - belly side; volar or palmar side are used in referring to the hand






24. Protection






25. In the direction away from the midline of a structure






26. Located between the cells and fibers - both of which are embedded in it; forms amorphous intercellar material; in fresh state - appears as a transparent and homogenous gel






27. Add support and strength; three types include collagen (white) - elastic (yellow) - and reticular fibers

35. A hook - shaped process or eminence






36. Farther from the point or origin of a structure or farther from the reference point or the midline axis






37. If the connective tissue layer is primarily composed of adipocytes - it is referred to as adipose tissue; round - large cell with distinct - dense nucleus; majority of cytoplasmic volume taken up by large lipid droplet; do not undergo mitosis; have a






38. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






39. Similar in structure and function as those in blood; agranular leukocytes migrate in large numbers under normal conditions
