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






2. A cavity






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






4. Referring to the same side of the body






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






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






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






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






9. 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)






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






11. 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)






12. A rough eminence - projection - or bump






13. A pulley mechanism






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






15. Similar to cilia; primary examples are human spermatozoa






16. 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






17. 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)






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






19. A pointed process






20. Prevents loss of water; protection






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






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






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






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






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






26. Secretion; absorption; protection; lubrication






27. 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






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






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






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






31. 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






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






33. A canal






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






35. Undifferentiated connective tissue cells which have the potential to differentiate into other types of connective tissue cells; primarily found in embryonic and fetal tissues; stellate shape; wandering cell






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






37. Supports body - protects organs - produces blood cells






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






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






40. Occur in areas involved in allergic reaction






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






42. Nonstriated - involuntary






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






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






45. Secretion; protection






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






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






48. Toward the back (the dorsum) of the body; think dorsal dolphin fin






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






50. A slit or gap
