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






2. Prevents loss of water; protection






3. Protection






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






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






6. Epithelium - connective tissue - muscle - nerve






7. Secretion; protection






8. A smooth - rounded articular surface






9. Secretion; absorption; protection; lubrication






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






11. Simple squamous - stratified squamous keratinized - stratified squamous nonkeratinized (moist) - simple cuboidal - stratified cuboidal - simple columnar - pseudostratified columnar - stratified columnar - transitional






12. In the direction of the cranium






13. 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)






14. A prominent - distinct area (the iliac crest)






15. A pointed process






16. Produces motions of body parts and viscera






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






18. Free surface






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






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






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






22. Protection






23. A slit or gap






24. Includes brain and spinal cord






25. 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






26. 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






27. A groove






28. Ducts of sweat glands; developing follicles of ovary






29. Referring to the same side of the body






30. Composed of several interrelated organ systems






31. 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)






32. Attached surface






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






34. 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






35. A shallow depression






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






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






38. Nearer the surface; without or nearer the outside of the body






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






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






41. Endothelium of blood and lymphatic vessels; bowman's capsule and thin loop of Henle in kidney; mesothelium lining pericardial - peritoneal - and pleural body cavities; lung alveoli; smallest excretory ducts of glands






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






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






44. Secretion; absorption; lines surface






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






46. Responds to internal and external stimuli; regulates and coordinates body activities and movements






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






48. A slit between bones; between the parietal bones of the skull - the slit is the superior sagittal fissure






49. Mucopolysaccharides (glycosaminoglycans) - proteins - lipids - and water






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