corticobulbar tract

The nerves within the corticobulbar tract are involved in movement in muscles of the head.

If the corticobulbar tract is affected a pseudobulbar affect with emotional changes may occur.

Also the corticobulbar tract is considered to be a pyramidal tract.

Many, but not all authors also consider the tracts to include the corticobulbar tracts.

This pathway from the cortex to the brainstem is called the corticobulbar tract.

The corticobulbar tract conducts impulses from the brain to the cranial nerves.

The corticobulbar tract also contributes to the motor regions of X in the nucleus ambiguus.

It receives upper motor neuron innervation directly via the corticobulbar tract.

The pyramidal tracts include both the corticospinal and corticobulbar tracts.

It contains the Corticobulbar tract.

When central facial palsy occurs, there are lesions in the corticobulbar tract between the cerebral cortex.

The corticobulbar tract is one of the pyramidal tracts, the other being the corticospinal tract.

The corticobulbar tract is composed of the upper motor neurons of the cranial nerves.

The pyramids house the pyramidal tracts-the corticospinal and the corticobulbar tracts of the nervous system.

It is caused by inadequate development of the corticobulbar tracts and causes problems with the mouth and tongue including impaired swallowing.

By virtue of involvement with the facial nerve, the corticobulbar tract is also responsible for transmitting facial expression.

Any lesion occurring within or affecting the corticobulbar tract is known as an upper motor neuron lesion.

Lesions of the genu of the internal capsule affect fibers of the corticobulbar tract.

The corona radiata is associated with the corticospinal tract, the corticopontine tract, and the corticobulbar tract.

With the exception of lower muscles of facial expression, all functions of the corticobulbar tract involve inputs from both sides of the brain.

The pyramidal pathways, such as corticospinal and some corticobulbar tracts, may directly innervate motor neurons of the spinal cord or brainstem.

(The corticonuclear tract is also called the corticobulbar tract, as the brainstem is sometimes called the "bulb" of the brain.)

The corticobulbar tract directly innervates the nuclei for cranial nerves V, VII, XI, and XII.

Another important finding is a false localizing sign, the so-called Kernohan's notch, which results from compression of the contralateral cerebral crus containing descending corticospinal and some corticobulbar tract fibers.

In contrast, pseudobulbar palsy describes impairment of function of cranial nerves IX-XII due to upper motor neuron lesions of the corticobulbar tracts in the mid-pons.
