| 1. | The medulla is above the decussation and the spinal cord below.
|
| 2. | Whereas damage below the pyramidal decussation will result in ipsilateral motor deficits.
|
| 3. | Decussation usually occurs 1-2 spinal nerve segments above the point of entry.
|
| 4. | :The decussation may be a survival trait.
|
| 5. | Damage to the body above the pyramidal decussation, will cause contralateral motor deficits.
|
| 6. | The pyramidal decussation marks the border between the spinal cord and the medulla oblongata.
|
| 7. | There is no decussation in the lateral corticospinal tract after the decussation at the medullary pyramids.
|
| 8. | There is no decussation in the lateral corticospinal tract after the decussation at the medullary pyramids.
|
| 9. | There, partial decussation occurs, and about 53 % of the fibers cross to form the optic tracts.
|
| 10. | Between the two pyramids can be seen a decussation of fibres which marks the transition from the medulla to the spinal cord.
