    • n ramus In biology, a branch or branching part, as of a plant, vein, artery, or forked bone. The rami of the ischium and pubis are their narrowed projecting parts. The rami of the lower jaw, as in man, are the ascending branches at each end, as distinguished from the intermediate horizontal part, called the body; but in any case where such distinction is not marked, as in birds and reptiles, a ramus is either half of the mandible, or one of the gnathidia, usually composed of several distinct bones. See diagram under bill, and cuts under Felidæ and pleurodont.
