The '''glottic cleft''' (rima glottidis) is surrounded by the '''arytenoid cartilages''' dorsally and '''vocal folds''' ventrolaterally. It varies in size and is diamond shaped. The glottic cleft disappears when the glottis is closed. Vocal folds run caudodorsally. The '''infraglottic cavity''' extends from the caudal section of the '''arytenoid cartilages''' into the lumen of the trachea. It is fixed in size. | The '''glottic cleft''' (rima glottidis) is surrounded by the '''arytenoid cartilages''' dorsally and '''vocal folds''' ventrolaterally.
