Description

Sanders writes that the brain of Ceratodus has the following general arrangement: The membrane which represents the pia mater is of great thickness and toughness; there are two regions where a tela choroidea is developed: one where it covers in the fourth ventricle, and the other where it penetrates through the third ventricle and separates the lateral ventricles from each other. The ventricles are all of large size, and the walls of the lateral ventricles are not completed by nervous tissue. The thalamencephalon and the mesencephalon are narrow, and the medulla oblongata is wide.
