Fig. 8.

Bipartite thyroarytenoid muscle and lateral laryngeal ventricle of an adult male Mongolian gazelle. Left lateral view. Main portion of epiglottis, left half of thyroid cartilage and cricothyroid muscle removed. In contrast to that in other bovids, the thyroarytenoid muscle is clearly divided into a rostral ventricularis and a caudal vocalis muscle. Between them, the two-chambered inflatable lateral laryngeal ventricle projects laterally. Scale bar is in millimetres. After Frey & Riede (2003).
