  1. Introduction to the Nervous System Neuro Quiz Identify the correct question Click to Play!  Michael McKeough 2008

  2. Introduction & OverviewNeuro Quiz Click category value to begin.

  3. Click to reveal the question Anatomical Divisions of NS 100 • This is the most caudal segment of the CNS. • It is subdivided in to cervical, thoracic, lumbar, and sacral. • It serves the somatic and visceral needs of the body. What is the spinal cord? Return to Game Board

  4. Click to reveal the question Anatomical Divisions of NS 200 • This segment is located between the spinal cord and pons. • It contains part of the reticular formation. • Longitudinal systems pass through here. • It contains cranial nerve nuclei: XII, XI, X IX, and parts of: VIII, VII, V. What is the medulla oblongata? Return to Game Board

  5. Click to reveal the question Anatomical Divisions of NS 300 • This segment contains the thalamus and hypothalamus. • It regulates most access to the cerebral cortex. • It is comprised of a constellation of nuclei. What is the diencephalon? Return to Game Board

  6. Click to reveal the question Anatomical Divisions of NS 400 • This structure is generally considered to be the highest level of the CNS. • The brain contains two of these. • It may be subdivided into four lobes. What are the cerebral hemispheres? Return to Game Board

  7. Click to reveal the question Anatomical Divisions of NS 500 • This structure consists of the medulla, pons and midbrain. • It contains the nuclei of all cranial nerves except CN I. • It controls the somatic and visceral functions of the head. • It controls the special senses of vision, audition, taste, and balance. What is the brainstem? Return to Game Board

  8. Click to reveal the question Information Functions of NS 100 • This event is defined as information by the NS. • It is sensed by specialized receptors. What is a significant energy changes in the environment? Return to Game Board

  9. Click to reveal the question Information Functions of NS 200 • Information is portrayed by the NS in this way. What is transient electrical activity along neurons? Return to Game Board

  10. Click to reveal the question Information Functions of NS 300 • This is the process by which information is detected from the environment. • This process is performed by specialized receptors. What is sensing? Return to Game Board

  11. Click to reveal the question Information Functions of NS 400 • This is the process by which the meaning of information is interpreted. • This process is performed by the cerebral cortex. What is perceiving? Return to Game Board

  12. Click to reveal the question Information Functions of NS 500 This is the purpose of output from a control center to its effector organs. What is initiating an adaptive action or response? Return to Game Board

  13. Click to reveal the question Divisions of the NS 100 • This division consists of the brain and spinal cord. What is the central nervous system? Return to Game Board

  14. Click to reveal the question Divisions of the NS 200 • This division consists of cranial nerves and spinal nerves. What is the peripheral nervous system? Return to Game Board

  15. Click to reveal the question Divisions of the NS 300 • This three layered membrane separates the central nervous system from the peripheral nervous system. What is the meninges? Return to Game Board

  16. Click to reveal the question Divisions of the NS 400 • This division is concerned with sensing and responding to changes in the external environment. What is the somatic nervous system? Return to Game Board

  17. Click to reveal the question Divisions of the NS 500 This division is concerned with sensing and responding to changes in the internal environment. What is the visceral nervous system? Return to Game Board

  18. Click to reveal the question Miscellaneous 100 • These structures possess the ability to generate and conduct electricity. • They perform the information processing functions of the NS. • They constitute the primary functional unit of the NS. What are neurons? Return to Game Board

  19. Click to reveal the question Miscellaneous200 • They consist of ascending and descending tracts that extend the length of the NS. • Together they constitute the long axis of the NS. • They are crossed. What are longitudinal systems? Return to Game Board

  20. Click to reveal the question Miscellaneous300 • This is a group of neurons that coalesce to control a particular aspect of behavior. • It is comprised of input, a control center, and output. • These form the fundamental organizational unit of the NS. What is a functional system? Return to Game Board

  21. Click to reveal the question Miscellaneous400 • This is the primary effect of aging on the NS. What is a progressive decline of function due to the loss of cells? Return to Game Board

  22. Click to reveal the question Miscellaneous500 • This is the side of the body on which signs and symptoms are seen following damage to the CNS. What is the opposite or contralateral side? Return to Game Board

  23. Click to reveal the question Organizational Principles 100 • They constitute the short axis of the NS. • They are uncrossed. • They serve the somatic and visceral functions of restricted regions of the head and body. What are segmental systems? Return to Game Board

  24. Click to reveal the question Organizational Principles 200 • This principle ensures that like information travels together in specialized tract inside the CNS. • It ensures that like information may be found in the same location at different levels of the NS. What is topographic organization? Return to Game Board

  25. Click to reveal the question Organizational Principles 300 • This principle results in most functional systems including a representation of the body surface. • Because of it the amount of space allocated to a particular body part is proportional to its control. What is somatotopic organization? Return to Game Board

  26. Click to reveal the question Organizational Principles 400 Because of this principle, older functional systems are located centrally and newer systems are located peripherally within the NS. What is phylogenetic organization? Return to Game Board

  27. Click to reveal the question Organizational Principles 500 • It is the most famous example of somatotopic organization in the nervous system. What is the homunculus? Return to Game Board
