Etymology: "Rostral" comes straight from Latin "rōstrum," meaning a beak, prow, or speaker's platform. The Romans used the word for the bronze-tipped ram at the front of a warship, the part that punched into an enemy hull, and for the raised platforms in the Forum from which orators addressed the crowd, which were decorated with the prows of captured ships. The shared image is a pointed projection at the leading edge of something. English adopted the Latin base, and the adjective "rostral" applies that same idea of leading edge to living bodies. In anatomy, it describes a structure or direction toward the front of an organism, especially the head end, much as a bird's beak sits at the front of its skull. The word thus keeps the original sense of forward-pointing projection, moving from naval engineering and public speaking to zoology and medicine.
