The lobes of the under surface of the cerebellum are shown in the next figure (304). It presents a rather complicated picture. In order to prepare specimens for this view the cerebellum must be severed from its connection with the midbrain,—, the anterior cerebellar peduncles must be severed, :—then from its connections with the pons and with the medulla and cord. Thus on each side there are the three cross-sections of the cerebellar peduncles. Between the anterior cerebellar peduncles lies a thin membrane,. Fig. 204.—The cerebellum. (Ventral aspect.) the velum medullare anticum, which is a part of the roof of the meten- cephalon. The cut surface of it is to be seen in the figure. The lobes on the ventral surface of the vermis are called:— 1. Nodulus. 2. Uvula. 3. Pyramis. 4. Tuber valvulce, making the boundary between the ventral and dorsal surface of the vermis (see Fig. 203). The lobes on the ventral surface of the hemispheres are:— 1. Flocculus, on each side of the nodulus and moored by the slender pedunculus flocculi. 2. Tonsilla, on either side of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Edinger, Ludwig, 1855-1918; Hall, Winfield Scott, b. 1861; Holland, Philo Leon; Carlton, Edward P.
