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. A vertical plane parallel to the midsagittal plane; it allows longitudinal slices that are parallel to the median plane






2. A smooth - rounded articular surface






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






4. 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






5. Accumulate in areas in response to chronic inflammation






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






7. Secretion; absorption; protection; lubrication






8. Simple - pseudostratified - stratified






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






10. 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






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






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






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






14. In the direction away from the midline of a structure






15. Occur in areas involved in allergic reaction






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






17. 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






18. In the direction of the head end of the body






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






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






21. A pulley mechanism






22. Prevents loss of water; protection






23. Ground substance - cells - fibers






24. 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)






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






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






27. 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






28. Striated - involuntary






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






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






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






32. Secretion; absorption; lines surface






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






34. Secretion; protection






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






36. Retractile fibers; thinner than collagen fibers;






37. Attached surface






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






39. If the connective tissue layer is primarily composed of adipocytes - it is referred to as adipose tissue; round - large cell with distinct - dense nucleus; majority of cytoplasmic volume taken up by large lipid droplet; do not undergo mitosis; have a






40. 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






41. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






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






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






44. Supports body - protects organs - produces blood cells






45. Organs and systems






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






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