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

2. Group of organisms that can interbreed.






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






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






5. 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.






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






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






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






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






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






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






12. 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.






13. Approved experiment directed toward developing a treatment.






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






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






16. 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.






17. Surgical removal of a cerebral hemisphere.






18. 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






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






20. 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.






21. Behavior that is characteristic of all members of a species.






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






23. 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.






24. 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.






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






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






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






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






29. 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.

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






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






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






34. 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.






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






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






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






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






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






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






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






42. 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.






43. 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.






44. Conducting away from the central nervous system structure.






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






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






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






48. 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.






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






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