Uberon definition : The third stomach of ruminants, situated on the right side of the abdomen at a higher
level than the fourth stomach and between this latter and the second stomach, with
both of which it communicates. From its inner surface project large numbers of leaves
or folia, each of which possesses roughened surfaces. In the center of each folium
is a band of muscle fibers which produces a rasping movement of the leaf when it contracts.

succeeeding parts of the alimentary canal. (Black's Veterinary Dictionary, 17th ed);
