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. Toward the front of the body - belly side; volar or palmar side are used in referring to the hand






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






3. Skeletal - smooth - cardiac






4. Located in the adventitia of blood vessels; multi - potential cells which may differentiate into various connective tissues or smooth muscle cells






5. Organs and systems






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






7. 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






8. Prevents loss of water; protection






9. Secretion; absorption; protection; lubrication






10. Epithelium - connective tissue - muscle - nerve






11. In the direction of the head; nearer the head






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






13. A groove






14. Secretion; protection






15. Simple - stratified






16. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






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






18. 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






19. Produces motions of body parts and viscera






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






21. Midsagittal or median; sagittal; frontal or coronal; transverse - horizontal - or cross






22. Free surface






23. A smooth - rounded articular surface






24. Male urethra; conjunctiva






25. 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)






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






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






28. Similar to cilia; primary examples are human spermatozoa






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






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






31. Retractile fibers; thinner than collagen fibers;






32. A shallow depression






33. Epidermis of skin






34. Nearer the surface; without or nearer the outside of the body






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






36. Occur in areas involved in allergic reaction






37. Secretion; protection; prevents loss of water






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






39. Person standing erect - feet together and parallel - face forward - arms at sides with palms facing forward (supinated)






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






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






42. 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






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






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






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






47. A rough eminence - projection - or bump






48. 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






49. Ground substance - cells - fibers






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