MICROANATOMY

Detailed explanation-1: -The dentate nucleus is the largest deep cerebellar cluster of neurons; it has a dentated – serrated – edge. Efferent fibers of the dentate nucleus are involved in the modulation of motor neurons and neurons involved in conscious thought and visuospatial function.

Detailed explanation-2: -The eight cerebellar nuclei, located within the deep white matter of each cerebellar hemisphere, are grouped into pairs, with one of each pair in each of the two hemispheres. As a chunk of tissue, the dentate nucleus with overlying cerebellar cortex makes up a functional unit called the cerebrocerebellum.

Detailed explanation-3: -The dentate nucleus is located within the cerebellar white matter and is directly adjacent to the vermis and the roof of the fourth ventricle bilaterally.

Detailed explanation-4: -From lateral to medial, the four deep cerebellar nuclei are the dentate, emboliform, globose, and fastigii.
