GENERAL HISTOLOGY

Detailed explanation-1: -From lateral to medial, the four deep cerebellar nuclei are the dentate, emboliform, globose, and fastigii.

Detailed explanation-2: -Efferent fibers of the dentate nucleus are involved in the modulation of motor neurons and neurons involved in conscious thought and visuospatial function. Disruption of the dentate nucleus is typically associated with cerebellar ataxia.

Detailed explanation-3: -As the oldest cerebellar nucleus, the fastigial nucleus (FN) plays essential roles in motor control by sending signals to the brainstem and eye movement nuclei and the maintenance of many activities within the human body, such as feeding, immune, and cardiovascular and respiratory functions.[1]

Detailed explanation-4: -Archicerebellum comprises of flocculonodular lobe and lingula and has mainly vestibular connections. It maintains equilibrium, tone and posture of trunk muscles. Paleocerebellum (spinal cerebellum) appears next in terrestrial vertebrates with the appearance of limbs.
