Exploration of the cerebellum and brain stem from the medial aspect

Midsagittal section

The midline representations of the lobular divisions of the cerebellum are visible in this section which cuts through the vermis. The third ventricle, cerebral aqueduct and fourth ventricle are demonstrated. Little detail is evident in the tegmentum of the medulla, pons and mesencephalon because the cut passes through the raphe.
