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. Protection






2. A rough eminence - projection - or bump






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






4. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






5. Heart






6. 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






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






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






10. A vertical plane in the antero - posterior direction which divides the body into equal right and left halves






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






12. A smooth - rounded articular surface






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






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






15. 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






16. In the direction of the nose (head)






17. In the direction of the feet; away from the head






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. Eye - ear - taste buds - and olfactory region






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






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






22. Secretion; absorption; lines surface






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






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






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






26. Similar to cilia; primary examples are human spermatozoa






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






28. Epithelium - connective tissue - muscle - nerve






29. 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






30. Very elongated microvilli






31. Male urethra; conjunctiva






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






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






34. In the direction of the tail end of the body or away from the head end






35. In the direction of the midline of a structure






36. Epidermis of skin






37. A canal






38. Supports body - protects organs - produces blood cells






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






40. Prevents loss of water; protection






41. A prominent - distinct area (the iliac crest)






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






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






44. Secretion; protection; prevents loss of water






45. 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)






46. Organs and systems






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






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






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






50. A pointed process
