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. Very elongated microvilli






2. Prevents loss of water; protection






3. 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






4. A pointed process






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






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. In the direction of the head end of the body






8. Striated - involuntary






9. 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






10. 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)






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






12. Nonstriated - involuntary






13. Chondroitin sulfate - hyaluronic acid (more)






14. 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






15. A hook - shaped process or eminence






16. Farther from the point or origin of a structure or farther from the reference point or the midline axis






17. Has compactly aggregated cells; has limited intercellular spaces and substance; is avascular (no blood vessels); lies on a connective tissue layer (the basal lamina); has cells that form sheets and are polarized; is derived from all three germ layers






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. A pulley mechanism






20. Occur in areas involved in allergic reaction






21. Referring to the opposite side of the body






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






23. Produces motions of body parts and viscera

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






26. Referring to the same side of the body






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






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






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






30. Similar to cilia; primary examples are human spermatozoa






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






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






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