risorius / risorious Explanation: Both spellings are found. Some info: "ri·so·ri·us. n, pl -rii: a narrow band of muscle fibers arising from the fascia over the masseter muscle, inserted into the tissues at the corner of the mouth, and acting to retract the angle of the mouth." (http://www.fasthealth.com/dictionary/r/risorius.php) "The Risorius muscles (Figs. 1,2, and 5) consist of narrow bundles of fibres which originate in the fascia over the Masseters and pass horizontally forward to be inserted in the skin of the corners of the mouth. These muscles vary considerably in size and shape. The action of the Risorius muscles is to retract the angle of the mouth." (http://www.sfu.ca/~saunders/l33098/L7/L7_1.html) HTH Andrea see above |
