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. In the direction of the head; nearer the head






3. Composed of several interrelated organ systems






4. A pulley mechanism






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






6. 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






7. Eye - ear - taste buds - and olfactory region






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






9. 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






10. In the direction of the midline of a structure






11. The sole of the foot






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






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






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






15. Secretion; absorption; protection; lubrication






16. Regulates body growth and function via hormones






17. Prevents loss of water; protection






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






19. Includes brain and spinal cord






20. Supports body - protects organs - produces blood cells






21. Simple - pseudostratified - stratified






22. Referring to the opposite side of the body






23. Nearer the midline of the body; toward the inside or interior






24. Striated - involuntary






25. Several organs which function together as a unit for a specific purpose.






26. Packing and supporting material of the body tissue and organs; develops from mesoderm (mesenchyme); all consist of the components ground substance - cells - and fibers






27. A rough eminence - projection - or bump






28. Fibroblasts - mesenchymal - macrophage (histiocytes) - adipocytes - mast - plasma - reticular - pericytes - and certain white blood cells or leukocytes (lymphocytes - monocytes - eosinophils - basophils - and neutrophils)






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






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






31. A canal






32. 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






33. 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






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






35. Retractile fibers; thinner than collagen fibers;






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






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






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






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






40. 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






41. In the direction of the cranium






42. 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)






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






44. Secretion; absorption; lines surface






45. Toward the front of the body - belly side; volar or palmar side are used in referring to the hand






46. A smooth - rounded articular surface






47. The outermost layer - composed of connective tissue with elastic and collagenous fibers - of an artery or another structure.






48. Simple - stratified keratinized - stratified nonkeratinized (moist)






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






50. 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
