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






2. Accumulate in areas in response to chronic inflammation






3. Organs and systems






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






5. Very elongated microvilli






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






7. 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






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






9. Includes peripheral nerves - ganglia - and receptors






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






11. 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)






12. Simple - stratified






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






14. 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)






15. Includes brain and spinal cord






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






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






18. Composed of several interrelated organ systems






19. 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)






20. Chondroitin sulfate - hyaluronic acid (more)






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






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






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






24. Simple - pseudostratified - stratified






25. Similar to cilia; primary examples are human spermatozoa






26. Secretion; protection






27. Heart






28. Nearer the midline of the body; toward the inside or interior






29. Retractile fibers; thinner than collagen fibers;






30. 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






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






32. Fibroblasts - mesenchymal - macrophage (histiocytes) - adipocytes - mast - plasma - reticular - pericytes - and certain white blood cells or leukocytes (lymphocytes - monocytes - eosinophils - basophils - and neutrophils)






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






34. Referring to the same side of the body






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






36. Attached surface






37. A slit or gap






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






39. Protection






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






41. Motile organelles extending into the lumen consisting of specifically arranged microtubules; mainly located in respiratory epithelium and part of female reproductive tract






42. A pointed process






43. 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






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






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






46. 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)






47. A shallow depression






48. A canal






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






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