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






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






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






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






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






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






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






9. 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.






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

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






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






13. Surgical removal of a cerebral hemisphere.






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






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






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






17. 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.






18. 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.






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






20. Conducting toward a central nervous system structure.






21. 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.






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






23. 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.

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






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






26. 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.






27. 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.






28. 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.

29. 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






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






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






32. Group of organisms that can interbreed.






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






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






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






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






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






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






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






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






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






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






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






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






45. 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.






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






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






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






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






50. Approved experiment directed toward developing a treatment.
