The anatomy of the nervous system, from the standpoint of development and function . ricle. Dorsal views. In Fig. 180 a triangular piece, including portions of the fornix,fimbria, and hippocampus, has been removed. the amygdaloid nucleus bulges into the terminal part of the inferior horn (). The floor and medial wall of the inferior horn are formed in large part 25° THE NERVOUS SYSTEM by the following structures, named in their order from within outward: thefimbria, hippocampus, and (in man) the collateral eminence (Figs. 181, 182,189). Upon the fimbria and hippocampus there is superimposed the chorioidplexus (Fig. 183). The hippocampus is a long, prominent, curved elevation,with whose medial border there is associated a band of fibers, representing acontinuation of the fornix and known as the fimbria.
