WebThe ventricular system of the brain represents an expansion of the central canal of the neural tube. As certain parts of the brain take shape, the central canal expands into well-defined ventricles, which are connected by thinner channels ( Fig. 11.37 ). The ventricles are lined by ependymal epithelium and are filled with clear cerebrospinal fluid.
