Here is a horizontal view of the Glottis : N, F, are the arytenoid cartilages, connected with the chordæ vocales, (vocal cords, or ligaments,) T, V, stretching across from the top of the arytenoid to the point of the thyroid cartilage : these cords can be elongated, and enlarged to produce lower sounds, and contracted and diminished for higher ones: and, at the same time, separated from each other, and allowing more condensed air to pass for the former purposes; or brought nearer together, to favor the latter: there are a great many muscles attached to the larynx, to give variety to the modifications of voice in speech and song
