These intrinsic muscles are the crico-ihyroid, the poderior crico-arytenoid, the lateral crico-arytenoid, thethyro-arytenoid, the arytenoid, and the aryteno-epiylottidean, togetherwith certain other slender muscular fasciculi. All these muscles, exceptthe arytenoid which crosses the middle line, are in pairs. The crico-tliyroid muscle (fig. 455, 10), is a short thick triangularmuscle, seen on the front of the larynx.
