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. A canal






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






3. Retractile fibers; thinner than collagen fibers;






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






5. Protection






6. Regulates body growth and function via hormones






7. A smooth - rounded articular surface






8. Kidney tubules; choroid plexus (lining of ventricles and spinal canal; produces CSF); thyroid gland; rete testis; surface of ovary






9. An outward bulging (hernia) of an organ etc. in a cavity or from a surface






10. A muscle's proximal attachment - or its fixed or less movable end' the origin is not constant and can be reversed






11. Protection






12. Secretion; absorption; lines surface






13. A hole in a bone; in the cranium - the spinal cord passes through the foramen magnum






14. In the direction of the nose (head)






15. The outermost layer - composed of connective tissue with elastic and collagenous fibers - of an artery or another structure.






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






17. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






18. Occur in areas involved in allergic reaction






19. Chondroitin sulfate - hyaluronic acid (more)






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






21. Removes body wastes from bloodstream; helps regulate homeostasis of internal environment






22. Secretion; protection






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






24. Located in the adventitia of blood vessels; multi - potential cells which may differentiate into various connective tissues or smooth muscle cells






25. Motile organelles extending into the lumen consisting of specifically arranged microtubules; mainly located in respiratory epithelium and part of female reproductive tract






26. Person standing erect - feet together and parallel - face forward - arms at sides with palms facing forward (supinated)






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






28. Migrate in large numbers into the interstitium during an inflammatory response






29. Toward the back (the dorsum) of the body; think dorsal dolphin fin






30. Secretion; absorption; protection; lubrication






31. Eye - ear - taste buds - and olfactory region






32. A vertical plane parallel to the midsagittal plane; it allows longitudinal slices that are parallel to the median plane






33. Very elongated microvilli






34. Composed of several interrelated organ systems






35. Lines lumen of respiratory tract (nasal cavity - trachea - and bronchi)(ciliated); ducts of epididymis (stereocilia); ductus (vas) deferens; male urethra






36. A pulley mechanism






37. A vertical plane which passes from side to side; it is at right angles to the midsagittal plane and cuts the specimen into anterior and posterior components (ear to ear)






38. Packing and supporting material of the body tissue and organs; develops from mesoderm (mesenchyme); all consist of the components ground substance - cells - and fibers






39. Produces motions of body parts and viscera






40. Away from the surface; within or toward the inside or interior






41. Several organs which function together as a unit for a specific purpose.






42. Ducts of sweat glands; developing follicles of ovary






43. A flat - smooth area (the articulating facet in vertebrae)






44. 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)






45. 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)






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






47. Found in inelastic structures; walls of blood vessels - lymphoid tissues (spleen and lymph nodes) - red bone marrow - basal laminae - and glands (liver - kidney)






48. A cavity






49. A prominence or ridge above an articular surface (condyle)






50. Contractile in nature and functions to move the skeletal system and body viscera.
