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






2. 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)






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






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






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






6. Skeletal - smooth - cardiac






7. Occur in areas involved in allergic reaction






8. Found in inelastic structures; walls of blood vessels - lymphoid tissues (spleen and lymph nodes) - red bone marrow - basal laminae - and glands (liver - kidney)






9. A hook - shaped process or eminence






10. Free surface






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






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






13. Retractile fibers; thinner than collagen fibers;






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






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






16. 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






17. Prevents loss of water; protection






18. A smooth - rounded articular surface






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






20. Organs and systems






21. In the direction of the midline of a structure






22. Secretion; absorption; protection; lubrication






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






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






25. Striated - voluntary






26. Referring to the opposite side of the body






27. Chondroitin sulfate - hyaluronic acid (more)






28. Removes body wastes from bloodstream; helps regulate homeostasis of internal environment






29. An inward bulging - depression - or bucketing of a cavity or from a surface






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






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






32. 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






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






34. Striated - involuntary






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






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






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






38. A shallow depression






39. Attached surface






40. A pointed process






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






42. 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)






43. Epithelium - connective tissue - muscle - nerve






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






45. Secretion; absorption; lines surface






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






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






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






49. Supports body - protects organs - produces blood cells






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