  • 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. Large collection of axons coursing together outside of the central nervous system.

2. Area of the skin supplied with afferent nerve fibers by a single spinal-cord dorsal root.

3. Floor (area below the ventricle) of the midbrain; a collection of nuclei with movement-related - species-specific - and pain-perception functions.

4. Behavior that is characteristic of all members of a species.

5. Fiber system connecting the two cerebral hemispheres to provide a route for direct communication between them.

6. Forbearer from which two or more lineages or family groups arise and so is ancestral to both groups.

7. Outer layer of brain-tissue surface composed of neurons; the human cerebral cortex is heavily folded.

8. Areas of the nervous system rich in fat-sheathed neural axons that form the connections between brain cells.

9. Large collection of axons coursing together within the central nervous system.

10. Cerebral cortex where visual processing begins - lying at the back of the brain ad beneath the occipital bone.

11. Movement related to sensory inputs - such as turning the head to see the source of a sound.

12. Sudden appearance of neurological symptom as a result of severe interruption of blood flow.

13. Process in which maturation is delayed - and so an adult retains infant characteristics; idea derived from the observation that newly evolved species resemble the young of their common ancestors.

14. Conducting toward a central nervous system structure.

15. Wound to the brain that results from a blow to the head..

16. Disorder of the motor system correlated with a loss of dopamine in the brain an characterized by tremors - muscular rigidity - and a reduction in voluntary movement.

17. Philosophical position that holds that behavior can be explained as a function of the nervous system without explanatory recourse to the mind.

18. Group of organisms that can interbreed.

19. A specialized 'nerve cell' engaged in information processing.

20. Central part of the brain that contains neural circuits for hearing and seeing as well as orienting movements.

21. Proposed nonmaterial entity responsible for intelligence - attention - awareness and consciousness.

22. Of the mind; an explanation of behavior as a function of the nonmaterial mind.

23. Part of the autonomic nervous system; acts in opposition to the sympathetic division- for example - preparing the body to rest and digest by reversing the alarm response or stimulating digestion.

24. Body plan in which organs or parts present on both sides of the body are mirror images in appearance.

25. The brain and spinal cord that together mediate behavior.

26. Cerebral Cortex often generally characterized as performing the brain's 'executive' functions - such as decision making - lying anterior to the central sulcus and beneath the frontal bone of the skull.

27. Disorder of the basal ganglia characterized by tics; involuntary vocalizations (including curse words and animal sounds); and odd - involuntary movements of the body; especially of the face and head.

28. Part of the PNS that regulates the functioning of internal organs and glands.

29. Three layers of protective tissue - dura mater - arachnoid - and pia mater - that encase the brain and spinal cord.

30. Roof (area above the ventricle) of the midbrain; its functions are sensory processing - particular visual and auditory - and the production of orienting movements.

31. Diencephalon structure through which information from all sensory systems is integrated into the appropriate region of the neocortex.

32. A small protrusion or bump formed by the folding of the cerebral cortex.

33. Diencephalon structure through which information from all sensory systems is integrated and projected into the appropriate region of the neocortex.

34. Neurosurgery in which electrodes implanted in the brain stimulate a targeted area with a low-voltage electrical current to facilitate behavior.

35. Clear solution of sodium chloride and other salts that fills the ventricles inside the brain and circulates around the brain and spinal cord beneath the arachnoid layer in the subarachnoid space.

36. Condition in which a person is alive but unable to communicate or to function independently at even the most basic level.

37. Condition in which a person can display some rudimentary behaviors - such as smiling - or utter a few words but is otherwise not conscious.

38. Surgical removal of a cerebral hemisphere.

39. The bones - or segments - that form the spinal column.

40. One of a set of 12 nerve pairs that control sensory and motor functions of the head - neck - and internal organs.

41. That holds that both a nonmaterial mind and the material body contribute to behavior.

42. Division into a number of parts that are similar; refers to the idea that many animals - including vertebrates - are composed of similarly organized body segments.

43. Evolutionarily the newest part of the brain; coordinates advanced cognitive functions such as thinking - planning - and language; contains the limbic system - basal ganglia - and the neocortex.

44. The 'between brain' that integrates sensory and motor information on its way to the cerebral cortex.

45. The general principle that sensory fibers are located dorsally and motors fibers are located ventrally.

46. Part of the central nervous system encased within the vertebrae (spinal column) tat provides most of the connections between the brain and the rest of the body.

47. Central structures of the brain - including the hindbrain - midbrain - thalamus - and hypothalamus - responsible for most unconscious behavior.

48. Evolutionarily the oldest part of the brain; contains pons - medulla - reticular formation - and cerebellum structures that coordinate and control most voluntary and involuntary movements.

49. Midbrain area in which nuclei and fiber pathways are mixed - producing a netlike appearance; associated with sleep-wake behavior and behavioral arousal.

50. The nervous system's potential for physical or chemical change that enhances its adaptability to environmental change and its ability to compensate for injury.
