Which part of the fornix is termed as the anterior part?

The anterior part of the fornix is referred to as the column of the fornix. The fornix is a major output tract of the hippocampus and consists of several distinct parts: the body, columns, crus, and pes. The columns extend downward toward the mammillary bodies, and this downward trajectory represents the anterior portion of the fornix.

The body of the fornix is positioned more centrally, connecting the columns with the crus. The crus of the fornix is part of the structure that curves laterally and posteriorly, while the pes hippocampi is the rounded end where the fornix starts to spread out to connect with the hippocampus. Thus, the column of the fornix is clearly identified as the anterior segment, as it plays a critical role in conducting signals from the hippocampus to the mammillary bodies, acting as a vital connection in the limbic system.
