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. 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.






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






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






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






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

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






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






8. 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.






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






10. 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.






11. 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.






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






13. Conducting away from the central nervous system structure.






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






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






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






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






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






19. 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.

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






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






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






23. 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.






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






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






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






27. 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.






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






29. 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.






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






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






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






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






34. Learned behaviors that are passed on from on generation to the next through teaching and experience.






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






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






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






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






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






40. 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.






41. 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.






42. 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.






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






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






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






46. 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.

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






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






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






50. 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.
