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. 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)






2. 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






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






4. Lines lumen of respiratory tract (nasal cavity - trachea - and bronchi)(ciliated); ducts of epididymis (stereocilia); ductus (vas) deferens; male urethra






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






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






7. A groove






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






9. 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)






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






11. A smooth - rounded articular surface






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






13. Includes peripheral nerves - ganglia - and receptors






14. In the direction of the nose (head)






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






16. Free surface






17. A slit or gap






18. Composed of several interrelated organ systems






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






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






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






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






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






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






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






26. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






27. 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






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






29. Supports body - protects organs - produces blood cells






30. Simple - stratified






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






32. 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






33. In the direction of the cranium






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






35. Attached surface






36. A prominence or ridge above an articular surface (condyle)






37. Chondroitin sulfate - hyaluronic acid (more)






38. 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)






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






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






41. Very elongated microvilli






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






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






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






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






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






47. 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






48. Occur in areas involved in allergic reaction






49. Organs and systems






50. Striated - involuntary
