distinctly seen after the cerebellum has been separated from the
medulla oblongata and pons. On either side of the nodule is a
thin layer of white substance, named the posterior medullary
velum. It is semilunar in form, its convex border being
continuous with the white substance of the cerebellum; it
extends on either side as far as the flocculus. The flocculus is
a prominent, irregular lobule, situated in front of the
biventral lobule, between it and the middle cerebellar peduncle.
It is subdivided into a few small laminæ, and is connected to
the inferior medullary velum by its central white core. The
flocculi, together with the posterior medullary velum and
nodule, constitute the lobus noduli.  The Uvula and
Tonsilla.—The uvula (uvula vermis; uvular lobe) forms a
considerable portion of the inferior vermis; it is separated on
either side from the tonsil by the sulcus valleculæ, at the
bottom of which it is connected to the tonsil by a ridge of gray
ma
