GENERAL HISTOLOGY

Detailed explanation-1: -The vermis classically is thought to be included within the “spinocerebellum” and to receive somatic sensory input from ascending spinal pathways. In contrast, the lateral zone of the cerebellum is included in the “cerebro-cerebellum” because it is densely interconnected with the cerebral cortex.

Detailed explanation-2: -Paleocerebellum (spinal cerebellum) appears next in terrestrial vertebrates with the appearance of limbs. It includes anterior lobe except lingula and pyramid and uvula. It is concerned with spinocerebellar connections and responsible for tone, posture and crude movements of the limbs.

Detailed explanation-3: -ˌpal-ē-plural paleocerebellums or paleocerebella-ˈbel-ə : a phylogenetically old part of the cerebellum concerned with maintenance of normal postural relationships and made up chiefly of the anterior lobe of the vermis and of the pyramid compare neocerebellum.

Detailed explanation-4: -The vermis (pl: vermes) of the cerebellum is an unpaired medial structure that separates the cerebellar hemispheres. Its anatomy broadly follows that of the cerebellar hemispheres.
