  • 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. Harry Jerison's quantitative measure of brain size obtained from the ratio of actual brain size to expected brain size - according to the principle of proper mass - for an animal of a particular body size.

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

3. Conducting away from the central nervous system structure.

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

5. Group of organisms that can interbreed.

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

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

8. Collection of nerve cells that function somewhat like a brain.

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

10. Hypothesis that the movements that we make and those that we perceive in others are essential features of our conscious behavior.

11. Phylogenetic tree that branches repeatedly - suggesting a taxonomy of organisms based on the time sequence in which evolutionary branches arise.

12. Areas of the nervous system composed predominantly of cell bodies and blood vessels that function either to collect and modify information or to support this activity.

13. A group of cells forming a cluster that can be identified with special stains to form a functional grouping.

14. Conducting toward a central nervous system structure.

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

16. Increase in the activity of a neuron or brain area.

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

18. Subcortical forebrain nuclei that coordinate voluntary movements of the limbs and body; connected to the thalamus and to the midbrain.

19. Degenerative brain disorder related to aging that first appears as progressive memory loss and later develops into generalized dementia.

20. Newest - outer layer (new bark) of the forebrain and composed of about six layers of gray matter that creates or reality.

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

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

23. Decrease in the activity of a neuron or brain area.

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

25. Surgical removal of a cerebral hemisphere.

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

27. Part of the PNS that includes the cranial and spinal nerves to and from the muscles - joints - and skin that produce movement - transmit incoming sensory input - and inform the CNS about the position and movement of body parts.

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

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

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

31. 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.

32. 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.

33. All the neurons in the body located outside the brain and the spinal cord; provides sensory and motor connections to and from the CNS

34. Approved experiment directed toward developing a treatment.

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

36. Disparate forebrain structures lying between the neocortex and the brainstem that form a functional system controlling affective and motivated behaviors and certain forms of memory; includes cingulate cortex - amygdala - hippocampus - among other str

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

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

39. Darwin's theory for explaining how new species evolve and how existing species change over time. Differential success in the reproduction of different characteristics (phenotypes) results from the interaction of organisms with their environment.

40. 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.

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

42. 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.

43. 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.

44. Part of the autonomic nervous system; arouses the body for action - such as mediating the involuntary fight-or-flight response to alarm by increasing hear rate and blood pressure.

45. Idea that selection for improved brain cooling through increased blood circulation in the brains of early hominids enabled the brain to grow larger.

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

47. General term referring to primates that walk upright - including all forms of humans - living and extinct.

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

49. 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.

50. Cerebral Cortex that functions to direct movements toward a goal or to perform a task - such as grasping an object - lying posterior to the central sulcus and beneath the parietal bone at the top of the skull.
