Subject : health-sciences
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. Major structure of the forebrain - consisting of two virtually identical hemispheres (left and right) and responsible for most conscious behavior.






2. 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.






3. 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.






4. 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.






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






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






7. 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.






8. Group of organisms that can interbreed.






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






10. 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.






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






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

13. 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.






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






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






16. Animal that has both a brain and a spinal cord.






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






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






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






20. 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.






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






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






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






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






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






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






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






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






29. 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.






30. 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.

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






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






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






34. 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.






35. 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.

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






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






38. 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.






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






40. A groove in brain matter - usually a groove found in the neocortex or cerebellum.






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






42. Conducting away from the central nervous system structure.






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






44. Approved experiment directed toward developing a treatment.






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






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






47. 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.






48. 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.






49. Surgical removal of a cerebral hemisphere.






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