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. Lubrication of body cavities to permit free movement of organs; pinocytotic transport across cells






2. Male urethra; conjunctiva






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






4. A shallow depression






5. Simple - pseudostratified - stratified






6. A smooth - rounded articular surface






7. Chondroitin sulfate - hyaluronic acid (more)






8. Skeletal - smooth - cardiac






9. Nearer the midline of the body; toward the inside or interior






10. Midsagittal or median; sagittal; frontal or coronal; transverse - horizontal - or cross






11. Secretion; protection; prevents loss of water






12. In the direction of the midline of a structure






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






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






15. Retractile fibers; thinner than collagen fibers;






16. A cavity






17. Epithelium - connective tissue - muscle - nerve






18. Regulates body growth and function via hormones






19. Epidermis of skin






20. Heart






21. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






22. Farther from the midline; toward the side of the body or away from the midsagittal plane; to the side






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






24. Striated - involuntary






25. Composed of neurons (cells); induces a response of distant muscles or glands; regulates body processes like respiration - circulation - and digestion






26. A rough eminence - projection - or bump






27. A vertical plane in the antero - posterior direction which divides the body into equal right and left halves






28. In the direction of the cranium






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






30. 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)






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






32. Star - shaped cells which join via their processes to form a cellular network; found abutting reticular fibers in certain glands and lymphoid tissues






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






34. Undifferentiated connective tissue cells which have the potential to differentiate into other types of connective tissue cells; primarily found in embryonic and fetal tissues; stellate shape; wandering cell






35. Mucosa of oral cavity - esophagus - anal canal - vagina; cornea of eye and part of conjunctiva






36. Walls of digestive tract and blood vessels - uterus - bladder






37. Protection






38. They are extremely elastic and are located in structures with a degree of elasticity such as the walls of blood vessels (elastic arteries) - true vocal cords - and trachea






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






40. Collagen (white) - elastic (yellow) - reticular






41. Attached surface






42. Includes brain and spinal cord






43. Secretion; protection






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






45. Ovoid cells with small round nuclei; cytoplasm contains numerous coarse basophilic granules (composed of histamine and heparin); Histamine dilates blood vessels and increases the permeability of capillaries - thus increasing interstitial fluid. Part






46. 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
