The brain does not simply grow, but rather develops in an intricately orchestrated sequence of stages.

BRAIN

Morphological subdivision facilitates topographical orientation in the cerebellum.This does not conform to functional divisions.The lingula is a small area of the vermis passing into the superior medullary velum.The tonsil is the oval shape at the bottom surface of the hemisphere.The folium vermis is a short band at the back of the vermis, appearing like a singular folium but actually marked with secondary fissures.The tuber vermis is the most posterior part of the inferior vermis.The nodule is the most anterior part of the inferior vermis.The flocculus is the most posterior part of the middle cerebellar peduncle, attached to the nodule via two thin spokes.

LESSON THEME

LESSON NUMBER

The sole sources of output from the cerebellum are the cerebellar nuclei.These nuclei receive inhibitory (GABAergic) inputs from Purkinje cells in the cerebellar cortex and excitatory (glutamatergic) inputs from mossy fiber and climbing fiber pathways. Most output fibers of the cerebellum originate from these nuclei.These nuclei are connected to the spinal cord, thus motor axons can manage and control physical activity.

FUNCTIONAL INVOLVEMENT

Grey matter refers to unmyelinated neurons and other cells of the central nervous system. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord.Grey matter is distributes at the surface of the cerebellum, as well as down the spinal cord.Grey matter contains most of the brain's neuronal cell bodies. The grey matter includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control.
