MCAT Human Body

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 30 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. In the direction of the midline of a structure






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






3. Occur in areas involved in allergic reaction






4. 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






5. 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)






6. A canal






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






8. 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






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






10. A shallow depression






11. Includes brain and spinal cord






12. Secretion; absorption; lines surface






13. Referring to the opposite side of the body






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






15. A rough eminence - projection - or bump






16. Cells lining lumen of digestive tract (stomach to rectum only); gall bladder; many glands (secretory units and ducts); uterus; uterine tube (ciliated)






17. 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






18. Attached surface






19. Simple - pseudostratified - stratified






20. A hole in a bone; in the cranium - the spinal cord passes through the foramen magnum






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






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






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






24. Striated - voluntary






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






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






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






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






29. Striated - involuntary






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






31. Kidney tubules; choroid plexus (lining of ventricles and spinal canal; produces CSF); thyroid gland; rete testis; surface of ovary






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






33. Protection






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






35. Star - shaped cells which join via their processes to form a cellular network; found abutting reticular fibers in certain glands and lymphoid tissues






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






37. Ground substance - cells - fibers






38. Secretion; protection; prevents loss of water






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






40. 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)






41. Epithelium - connective tissue - muscle - nerve






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






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






44. A groove






45. A slit or gap






46. 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






47. 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)






48. Chondroitin sulfate - hyaluronic acid (more)






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






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