It corresponds to what has been known asthe superior and inferior semilunar lobules and the biventral lobule (Figs. 146, 147). Thelobulus paramedianus, or tonsilla of the B. N. A., is located on the lateral surface of thesheeps cerebellum, but is displaced on to the caudal surface in man by the great expansionof the lobulus ansiformis. 202 THE NERVOUS SYSTEM The posterior lobe, as outlined by Ingvar, is composed of median and lateral median part, known as the posterior median lobule, comprises all of the inferior vermisexcept the tuber, from which it is separated by the prepyramidal sulcus. It is subdividedinto three sublobules, known as the nodule, uvula, and pyramid (Figs. 139, 141, 145). Thelateral part of the posterior lobe
