Anatomical terminology

Fastigius is an adjective based on the Latin fastigium, meaning summit. Thus it is used to refer to the peak of the fourth ventricle.;^[1] closely related to the posterolateral fissure, which divide the lingula from the nodulus of the cerebelar vermis. See also nucleus fastigius, or more commonly, nucleus fastigii or fastigial nucleus.
