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






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






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






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






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






6. 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.






7. 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.






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






9. Group of organisms that can interbreed.






10. 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.


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






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






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






14. 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






15. Conducting toward a central nervous system structure.






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






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






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






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






20. Conducting away from the central nervous system structure.






21. 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.






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






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






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






25. Approved experiment directed toward developing a treatment.






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






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






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






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






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






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






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






33. 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.






34. 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.






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






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






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






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






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






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






42. 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.






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






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






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






46. Surgical removal of a cerebral hemisphere.






47. 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.






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






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






50. 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.
