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. 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.






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






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






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






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






6. 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.






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

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






9. Simple nervous system that has no brain or spinal cord but consists of neurons that receive sensory information and connect directly to other neurons that move muscles.






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






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






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






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






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






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






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






17. 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.






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






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






20. 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.






21. 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.






22. Surgical removal of a cerebral hemisphere.






23. 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.

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






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






26. 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.






27. 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.






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






29. Approved experiment directed toward developing a treatment.






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






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






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






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






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






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






36. 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.






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






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






40. 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.






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






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






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






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






45. Group of organisms that can interbreed.






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






47. 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.






48. 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.






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






50. 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.
