| 11. | This aponeurosis formed from fibres from either side of the external oblique decussates at the linea alba.
|
| 12. | The petioles and held in a decussate pairs, but twisted so they lie in one plane.
|
| 13. | These neurons decussate to the opposite side ( anterolateral ), and travel up the spinal column.
|
| 14. | It is still undetermined if the spinoreticular tract possesses ipsilateral fibers in addition to those that decussate.
|
| 15. | The rest is densely spirally striate, with light incremental lines which decussate the lirulae, especially beneath.
|
| 16. | The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups.
|
| 17. | At this point, second order neurons decussate and relay information through the contralateral medial lemniscus to the thalamus.
|
| 18. | Then the fibers decussate and form the middle cerebellar peduncle, terminating in the cerebellar cortex as mossy fibers.
|
| 19. | The neurons in the optic nerve decussate in the optic chiasm with some crossing to the contralateral optic nerve tract.
|
| 20. | The fibers that do not decussate will pass through the medulla and continue on to form the anterior corticospinal tracts.
