Ugula Cerebellum

**Cerebellar uvula (Sylvius line) –** is the medial part in the posterior part of the posterior commissure of the cerebellum, where it branches into another part - the visceral mastoid process. The anterior and posterior commissures of the interventricular foramen of the cerebellum have the most clear outlines, and the interpontine foramen is formed most indistinctly, due to the fact that its walls coincide with the walls of the third ventricle. The posterior commissure of the cerebellum is oriented vertically, forming a continuation of the vertical column of the cerebellum. A thin, weakly defined lower horizontal part of the outer surface of the hemispheres begins, penetrating between the posterior peduncles of the cerebellum and ending in the posterior perforated substance. Further, the branch continues in the form of a tongue of the brain, which forms a thin longitudinal strip of membranes at the posterior end of the posterior inclined opening. From above, the layer of membranes converges with the outer occipital bone and, through a thin strip, passes into the posterior cortex. The lower horizontal and lateral part of the cerebellar uvula begins from the membrane between the cerebellar tooth; it emerges from the cerebellum in the perisellar region on the superior surface of the body of the sphenoid bone between the body and the wing. Between the posterior cortex and the body of the sphenoid bone lies the neuralgia of the pharyngeal nerve.
