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. Protection






2. Nonstriated - involuntary






3. Produces motions of body parts and viscera






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






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






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






7. 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






8. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






9. 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)






10. Away from the center of the body; toward the outside






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






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. Epithelium - connective tissue - muscle - nerve






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






15. In the direction of the nose (head)






16. Away from the surface; within or toward the inside or interior






17. Have eccentric nucleus with chromatin in a cartwheel pattern; found in lamina propira of gastrointestinal tract; function in protecting body against bacterial invasion by secreting antibodies (immunoglobulins - IgG) into the circulating blood






18. Composed of several interrelated organ systems






19. 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






20. A slit or gap






21. 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






22. A pulley mechanism






23. Lines lumen of respiratory tract (nasal cavity - trachea - and bronchi)(ciliated); ducts of epididymis (stereocilia); ductus (vas) deferens; male urethra






24. A vertical plane parallel to the midsagittal plane; it allows longitudinal slices that are parallel to the median plane






25. Secretion; absorption; protection; lubrication






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






27. Very elongated microvilli






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






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






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






31. Heart






32. 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






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






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






35. The sole of the foot






36. Epidermis of skin






37. 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






38. Includes peripheral nerves - ganglia - and receptors






39. Skeletal - smooth - cardiac






40. Simple - stratified keratinized - stratified nonkeratinized (moist)






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






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






43. Prevents loss of water; protection






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






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






46. Chondroitin sulfate - hyaluronic acid (more)






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






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






49. Structures that are subjected to pull or stretching activities such as tendons - ligaments - aponeuroses (a sheet - like tendinous expansion - like in hand) and fascia






50. Accumulate in areas in response to chronic inflammation
