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






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






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






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






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






6. 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.






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






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






9. Conducting away from the central nervous system structure.






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






11. Conducting toward a central nervous system structure.






12. 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.






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






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






15. 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.






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






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






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. 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.






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






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






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






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






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






25. 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.






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






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






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






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






30. 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.






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






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






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






34. 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.


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






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






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






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






39. 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.






40. 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.






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






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






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






45. 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






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






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






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






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






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