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






2. Epithelium - connective tissue - muscle - nerve






3. 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






4. Includes peripheral nerves - ganglia - and receptors






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






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






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






8. Ground substance - cells - fibers






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






10. 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






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






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






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






14. In the direction of the nose (head)






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






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






17. Prevents loss of water; protection






18. Chondroitin sulfate - hyaluronic acid (more)






19. A cavity






20. 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






21. Urinary tract (renal calyces and pelvis - ureter - and urinary bladder)






22. Composed of several interrelated organ systems






23. 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)






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






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






26. Male urethra; conjunctiva






27. 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)






28. Secretion; protection; prevents loss of water






29. Supports body - protects organs - produces blood cells






30. 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)






31. Occur in areas involved in allergic reaction






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






33. 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






34. A canal






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






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






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






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






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






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






41. Striated - involuntary






42. 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






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






44. 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






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






46. A slit or gap






47. Similar to cilia; primary examples are human spermatozoa






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






49. Simple - pseudostratified - stratified






50. Secretion; absorption; protection; lubrication
