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






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






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






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






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






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






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






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






9. Responds to internal and external stimuli; regulates and coordinates body activities and movements






10. 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)






11. Occur in areas involved in allergic reaction






12. Secretion; absorption; lines surface






13. A cavity






14. 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






15. A hook - shaped process or eminence






16. Primarily attached and nonmotile (fixed cells) but some have the ability to move (wandering or free cells); typical cells found in connective tissue are fibroblasts - mesenchymal - macrophage (hisitocytes) - adipocytes - mast - plasma - reticular - p






17. Secretion; absorption; protection; lubrication






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






19. Free surface






20. 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






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






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






23. A rough eminence - projection - or bump






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






25. A pulley mechanism






26. Very elongated microvilli






27. 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)






28. Limits and protects the body as a whole; prevents excess loss of water; functions in regulating body temperature






29. Retractile fibers; thinner than collagen fibers;






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






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






32. In the direction of the midline of a structure






33. Secretion; protection






34. Epidermis of skin






35. 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






36. A shallow depression






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






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






39. Accumulate in areas in response to chronic inflammation






40. An outward bulging (hernia) of an organ etc. in a cavity or from a surface






41. Organs and systems






42. Protection






43. 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






44. Ducts of sweat glands; developing follicles of ovary






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






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






47. Striated - voluntary






48. Perpetuates the living organism by the production of sex cells (gametes) and future offspring






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






50. The distal end; the less fixed and more movable end of a muscle attachment
