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






2. Enzymatically breaks down food materials into usable and absorbable nutrients






3. Includes brain and spinal cord






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






5. In the direction of the midline of a structure






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






7. Secretion; protection; prevents loss of water






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






9. Cells and fibers embed into it; acts as a route for the passage of nutrients and wastes to and from the cells within or adjacent to the connective tissue






10. Covers the external surfaces of the body and lines the internal tubes and cavities; forms glands






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






12. Striated - involuntary






13. The distal end; the less fixed and more movable end of a muscle attachment






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






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






16. A canal






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






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






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






20. In the direction of the feet; away from the head






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






22. 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






23. 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)






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






25. Attached surface






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






27. A horizontal plane at right angles to both the sagittal and frontal plane; it cuts the specimen into superior (upper or cephalad) and inferior (lower or caudad) portions; cross sections of the specimen (cuts at waist)






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






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






30. In the direction of the nose (head)






31. 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






32. Includes peripheral nerves - ganglia - and receptors






33. Heart






34. 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






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






36. Simple - stratified






37. Each has a definite function which results from the combined functions of the various tissue components.






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






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






40. Referring to the same side of the body






41. Chondroitin sulfate - hyaluronic acid (more)






42. Secretion; protection; facilitates transport of substances on surface of cells






43. Consists of a group of cells performing a similar function






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






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






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






47. 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)






48. A groove






49. Protection






50. Accumulate in areas in response to chronic inflammation
