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






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






3. A slit between bones; between the parietal bones of the skull - the slit is the superior sagittal fissure






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






5. Regulates body growth and function via hormones






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






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






8. Nonstriated - involuntary






9. 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






10. 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






11. In the direction of the nose (head)






12. 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






13. A horizontal plane at right angles to both the sagittal and frontal plane; it cuts the specimen into superior (upper or cephalad) and inferior (lower or caudad) portions; cross sections of the specimen (cuts at waist)






14. An outward bulging (hernia) of an organ etc. in a cavity or from a surface






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






16. 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)






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






18. A pulley mechanism






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






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






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






22. Prevents loss of water; protection






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






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






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






26. A hook - shaped process or eminence






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






28. Migrate in large numbers into the interstitium during an inflammatory response






29. Composed of several interrelated organ systems






30. Lymphocytes - monocytes - eosinophils - basophils - neutrophils






31. Similar in structure and function as those in blood; agranular leukocytes migrate in large numbers under normal conditions






32. Very elongated microvilli






33. Ducts of sweat glands; developing follicles of ovary






34. A shallow depression






35. A slit or gap






36. Includes peripheral nerves - ganglia - and receptors






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






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






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






40. The sole of the foot






41. 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






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






43. Kidney tubules; choroid plexus (lining of ventricles and spinal canal; produces CSF); thyroid gland; rete testis; surface of ovary






44. Walls of digestive tract and blood vessels - uterus - bladder






45. Limits and protects the body as a whole; prevents excess loss of water; functions in regulating body temperature
