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. Secretion; absorption; lines surface






2. A cavity






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






4. Structures that are subjected to pull or stretching activities such as tendons - ligaments - aponeuroses (a sheet - like tendinous expansion - like in hand) and fascia






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






6. Produces motions of body parts and viscera






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






8. A smooth - rounded articular surface






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. 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






11. Epithelium - connective tissue - muscle - nerve






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






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






14. Protection






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






16. Consists of a group of cells performing a similar function






17. Secretion; protection; prevents loss of water






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






19. 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






20. Simple - pseudostratified - stratified






21. Away from the surface; within or toward the inside or interior






22. A slit or gap






23. Ground substance - cells - fibers






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






25. Composed of several interrelated organ systems






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






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






28. Organs and systems






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






30. 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






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






32. The sole of the foot






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






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






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






36. Simple squamous - stratified squamous keratinized - stratified squamous nonkeratinized (moist) - simple cuboidal - stratified cuboidal - simple columnar - pseudostratified columnar - stratified columnar - transitional






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






38. Retractile fibers; thinner than collagen fibers;






39. A canal






40. Contractile in nature and functions to move the skeletal system and body viscera.






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






42. Toward the back (the dorsum) of the body; think dorsal dolphin fin






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






44. 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






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






46. Prevents loss of water; protection






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. 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






49. 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
