Explanation:
Detailed explanation-1: -The most prominent ones are the horizontal, posterolateral, postlunate, primary and retrotonsillar fissures. These fissures divide the cerebellum into three main lobes, which are the anterior, posterior and flocculonodular lobes. In addition to the lobes, the cerebellar hemispheres consist of lobules.
Detailed explanation-2: -horizontal fissure (GHF) or horizontal sulcus of the cerebellum represents a landmark which divides the cerebellar hemispheres into superior and inferior portions. In our experience, the fissure can be visualized on most selective vertebral angiograms of excellent quality.
