How is bulbar paralysis caused?

summary

Bulbar paralysis is called bulbar paralysis, also called true bulbar paralysis. When the motor nucleus in the medulla oblongata, or the cranial nerve from the medulla oblongata (including glossopharyngeal nerve, vagus nerve and hypoglossal nerve) causes paralysis, a group of symptoms appear, mainly including drinking water, eating, choking, dysphagia, hoarseness or aphasia. How is bulbar paralysis caused? Next, I'd like to share my views with you.

How is bulbar paralysis caused?

The IX, x, Xi, Ⅻ pairs of cranial nerves from the medulla oblongata are called posterior group cranial nerves. Their main function is to control the movement of glossopharynx. After being damaged, they can lead to speech and swallowing disorders. The causes of bulbar paralysis can be vascular diseases, inflammatory tumors, degenerative diseases, autoimmune diseases and so on.

Medulla oblongata palsy can be either the total palsy of the ninth, tenth, eleventh and twelfth nerves, or partial or individual nerve palsy. The lesion sites include lower motor neurons, upper motor neurons and muscles.

Nerve IX, X and Xi are innervated by bilateral cortical brainstem tracts. Unilateral cortical brainstem tract damage may be asymptomatic, and bilateral damage may lead to pseudobulbar palsy. Nerve Ⅻ is innervated by contralateral unilateral cortical brainstem tract. Unilateral supranuclear, nuclear and subnuclear damage can lead to unilateral supranuclear or subnuclear hypoglossal nerve palsy, and bilateral damaged tongue can not move.
