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. 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






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






3. A smooth - rounded articular surface






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






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






6. The sole of the foot






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






8. Produces motions of body parts and viscera






9. Prevents loss of water; protection






10. Regulates body growth and function via hormones






11. Secretion; absorption; lines surface






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






13. 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)






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






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






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






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






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






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






20. Epithelium - connective tissue - muscle - nerve






21. Male urethra; conjunctiva






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






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






24. 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






25. Secretion; absorption; protection; lubrication






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






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






28. The outermost layer - composed of connective tissue with elastic and collagenous fibers - of an artery or another structure.






29. Includes brain and spinal cord






30. A shallow depression






31. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






32. Simple - pseudostratified - stratified






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






34. Retractile fibers; thinner than collagen fibers;






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






36. Composed of several interrelated organ systems






37. A canal






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






39. Striated - voluntary






40. 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)






41. 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






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






43. Walls of digestive tract and blood vessels - uterus - bladder






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






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