It is usual to describe it as being composed of a body and three horns, viz. an anterior, a posterior, and an inferior horn. The cornu anterius is that part of the cavity which lies in front of the interventricular foramen.

The cornu anterius is that part of the cavity which lies in front of the interventricular foramen. The body or pars centralis is the portion of the ventricle which extends from the interventricular foramen to the splenium of the corpus callosum. At this point the posterior and inferior horns diverge from the posterior part of the body. The cornu posterius curves backwards and medially into the occipital lobe. It is very variable in its length and capacity: the chief reason for this variability is that adhesions between the walls of this part of the ven- tricle are of common occur- rence. The cornu inferius proceeds with a bold sweep round the posterior end of the Fig. 561.—Drawing takes from a Cast of the Ventricular thalamus, and then tunnels in SySTEM 0F THE BRAiy> as seeu from above- <After Retzius-^ a forward and medial direction Vent.

The early foetal lateral ven- tricle is very capacious and presents an arched or semi- lunar form. It is composed of parts which correspond to the anterior horn, the central part and the in- ferior horn, and there is little or no demarcation between them. The posterior horn is a later production.
