Abstract: The weights of some intrinsic laryngeal and palatine muscles from 46 thoroughbred horses of varying ages are presented. These horses had no clinical history of wind affliction. The muscles studied were the dorsal cricoarytenoid, the lateral cricoarytenoid, the cricothyroid, the palatine levator and the palatine tensor. The muscles supplied by the left recurrent laryngeal nerve tended to be lighter in older horses than the muscles supplied by the right recurrent laryngeal nerve. However there was no significant difference in weight between the left and right side for all muscles studied except the lateral cricoarytenoid. In this muscle the left side was significantly lighter than the right (P<0.001).
