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. Most numerous type; collagen bundles are strong and resist stretching






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






3. Epidermis of skin






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






5. Has compactly aggregated cells; has limited intercellular spaces and substance; is avascular (no blood vessels); lies on a connective tissue layer (the basal lamina); has cells that form sheets and are polarized; is derived from all three germ layers






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






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






8. Organs and systems






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






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






11. Skeletal - smooth - cardiac






12. Primarily attached and nonmotile (fixed cells) but some have the ability to move (wandering or free cells); typical cells found in connective tissue are fibroblasts - mesenchymal - macrophage (hisitocytes) - adipocytes - mast - plasma - reticular - p






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






14. Free surface






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






16. Secretion; protection; prevents loss of water






17. 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






18. Can be fixed or free; fixed are numerous in loose connective tissue; polymorphic shape with oval nucleus; have the ability to engulf extracellular material (foreign matter or necrotic cells)






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






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






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






22. Nearest a point of origin in general or nearest the trunk as far as the extremities are concerned; nearer the attachment to the body; nearer the midline axis






23. Very elongated microvilli






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






25. A cavity






26. 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)






27. 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






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






29. Respond to external and internal stimuli and have the capability to transmit a message (impulse) from one area of the body to another






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






31. A rough eminence - projection - or bump






32. Composed of several interrelated organ systems






33. Dilates blood vessels and increases the permeability of capillaries - thus increasing interstitial fluid.






34. Similar to cilia; primary examples are human spermatozoa






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






36. Most common; called fibrocyte when in flattened stellate state






37. 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






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






39. Simple - stratified






40. In the direction of the nose (head)






41. In the direction of the cranium






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






43. Transports nutrients - wastes - gases (oxygen and carbon dioxide)hormones - blood cells throughout body; protects body against foreign organisms






44. Attached surface






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






46. Retractile fibers; thinner than collagen fibers;






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






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






49. A hook - shaped process or eminence






50. Occur in areas involved in allergic reaction
