The terminal ventricle is a dilation of the ventricular system located within the spinal cord, which is enveloped in ependymal cells that are involved in the dynamic of the cerebrospinal liquid. In the present study, four

The central nervous system has five ventricles [1], where the fifth is located on the most caudal (inferior) portion of the spinal cord [1, 2], and is a dilation of the central canal, which is named as terminal ventricle [2, 3]. This has been identified in a number of species, which range from rays, such as
In humans, terminal ventricle is located at the conus medullaris [10-14], and is enveloped by ependymal cilia cells [3, 11], similar to
