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

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

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

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

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

6. 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.

7. 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.

8. 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.

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

10. 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.

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

12. 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.

13. Quandary of explaining a nonmaterial mind in command of a material body.

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

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

16. 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.

17. Conducting away from the central nervous system structure.

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

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

20. Literally - half a sphere - referring to one side of the cerebral cortex or of one side of the cerebellum.

21. Synonym for mind - an entity once proposed to be the source of human behavior.

22. Group of organisms that can interbreed.

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

24. Conducting toward a central nervous system structure.

25. 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.

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

27. Cortex that functions in connection with hearing - language - and musical abilities and lies below the lateral fissure - beneath the temporal bone at the side of the lobe.

28. Major structure of the brainstem specialized for coordinating and learning skilled movements. In large-brained animals - it may also have a role in the coordination of other mental processes.

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

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

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

32. 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.

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

34. 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.

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

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

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

38. One of four cavities in the brain that contain cerebrospinal fluid that cushions the brain and may play a role in maintaining brain metabolism.

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

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

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

42. 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.

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. Map of the neocortex based on the organization - structure - and distribution of the cells.

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

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

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

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

49. 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.

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