It receives upper motor neuron innervation directly via the corticobulbar tract.
2.
The corticobulbar tract conducts impulses from the brain to the cranial nerves.
3.
The corticobulbar tract is composed of the upper motor neurons of the cranial nerves.
4.
If the corticobulbar tract is affected a pseudobulbar affect with emotional changes may occur.
5.
Many, but not all authors also consider the tracts to include the corticobulbar tracts.
6.
The "'pyramidal tracts "'include both the corticospinal and corticobulbar tracts.
7.
Any lesion occurring within or affecting the corticobulbar tract is known as an upper motor neuron lesion.
8.
When central facial palsy occurs, there are lesions in the corticobulbar tract between the cerebral cortex.
9.
Berne and Levy say, " Much of the corticobulbar tract belongs to the medial system ".
10.
The corticobulbar tract innervates cranial motor nuclei bilaterally with the exception of the lower facial nuclei which are innervated only unilaterally ( below the eyes ) and X in the nucleus ambiguus.
