Across
  1. 4. a central nervous system disorder in which brain activity becomes abnormal, causing seizures or periods of unusual behavior, sensations, and sometimes loss of awareness
  2. 6. 10th cranial nerve
  3. 9. the inability to execute rapidly alternating movements, particularly of the limbs. It is most readily demonstrated by asking the patient to pronate and supinate an arm at speed, with a tap on the opposite forearm at the extremes of movement
  4. 10. Flex the patients leg at both hip and knee, then straighten knee. Pain and increased resistance to extending the knee are a positive sign, this may indicate subarachnoid hemorrhage or meningitis. (2)
  5. 13. a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing (2)
  6. 16. This cranial nerve transmits the sense of smell
  7. 21. Upper most part of the brain, contains two large hemispheres
  8. 22. Slows the heart rate and respiration, speeds up digestion "rest and digest"
  9. 23. The sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain
  10. 26. This acronym has been used by the National Stroke Association, American Heart Association and others to educate the public on detecting symptoms of a stroke.
  11. 28. The membranous coverings of the brain and spinal cord, there are three layers
  12. 29. There are 12 pairs of these nerves
  13. 30. This is a test of postion sense, positive when the patient sways and loses balance with eyes closed
Down
  1. 1. a condition that causes a temporary weakness or paralysis of the muscles in the face. It can occur when the nerve that controls your facial muscles becomes inflamed, swollen, or compressed (2)
  2. 2. This cranial nerve receives sensation from the face and innervates the muscles of mastication
  3. 3. this cranial nerve provides motor innervation to the muscle of the tongue
  4. 5. an infection of the protective membranes that surround the brain and spinal cord.
  5. 7. Terminates between 1st and 2nd lumbar vertebra (2)
  6. 8. Delicate serous membrane, a potential space above and arachnoid space below filled with CSF (2)
  7. 11. This chart can test for visual acuity
  8. 12. Link joining all parts of the brain (2)
  9. 14. Delicate membrane supplied with blood vessels, adherent to the brain surface (2)
  10. 15. Drooping of the eyelid
  11. 17. As you flex the neck, watch the hips and knees which should remain relaxed. Flexion of both hips and knees is a positive sign, this may be used for detecting meningitis. (2)
  12. 18. Stimulates and quickens the heart, circulatory and respiratory "fight or flight"
  13. 19. Involuntary rapid eye movement
  14. 20. a temporary blockage of blood flow to the brain.
  15. 23. Controls automatic and learned functions such as balance, muscle co-ordination and posture
  16. 24. Tough fibrous double membrane with a potential space (2)
  17. 25. indicates abnormal function of the corticospinal tract in the contralateral hemisphere. In some patients, the arm may remain supinated but drop lower than the unaffected arm, and the fingers and elbow might flex (2)
  18. 27. There are 31 pairs of these nerves
