Lobule VIIIA vermis

This is the small posterior most part of the vermis and seems to take only half of the posterior most white matter trunk.
It was the lobule that was present in the most lateral slices of the vermis and appeared to meet lobule XIIIA in the axial plane.It was best delineated in the sagittal plane.

This lobule is the other half of the posterior most white matter branch and is present, laterally, nearly as long as Lobule VIIIA. It was also best delineated in the sagittal plane.

This lobule is a triangular shape and is bordered on one side by Lobule VIIIB and on the other by X.
It is the largest lobe in the sagittal view of the midline. The border between IX and X is a fissure that reached the CM and can be determined by considering the difference in the branches on either side. It was best delineated in the sagittal plane.

Lobule X is the anterior most lobule of the vermis and contained no fissures. It is present in more lateral slices than lobule IX but only barely.
The fissure separating lobules IX and X often grew as one progressed laterally in the sagittal view, and these lobules would sometime be separated by Lobule IX of the hemisphere.
Lobule X of the vermis is disjoint from lobule X of the hemisphere. This was also best delineated in the sagittal view.
