- 47. Sudden transient mechanical head injury with disruption of neural activity and a change in the LOC
- 48. Chemicals that affect the transmission of impulses across the synaptic cleft
- 49. Major relay center for afferent inputs to the cerebral cortex
- 50. Chemicals that affect the transmission of impulses across the synaptic cleft
Down
- 2. Occurs when an embolus lodges in and occludes a cerebral artery, resulting in infarction and edema of the area supplied by the involved vessel

- 8. one-sided musle paralysis or weakness
- 9. inability to prodce language
- 13. Produced in several areas of brain. Involved in emotions and moods and regulating motor control
- 16. Results from inadequate blood flow to the brain from partial or complete occlusion of an artery
- 18. Found primrily in gray matter and provide structiral support to neurons
- 21. Bleeding int h subthalamic areas of the brin (problem with vision an eye movement)
- 22. Account for approximately 15% of all strokes. Result from bleeding into the brain tissue itself
- 23. occurs when a mass lesion in the cerebrum forces the brain to herniate downward through the opening created by the brainstem
- 24. Usually occurs within the frontal and temporal lobes, possibly from rupture of intracerebral vessels at the time of injury
- 26. Carrie nerve impulses to other neurons or to end organs
- 27. The inability to carry out learned sequential movements on command
- 29. Thin wall of dura that folds down between the cortex, separating the two cerebral hemispheres
