Abstract
Extract
Recent work (Gunn, Citation1972, Citation1973; Duncan and Griffiths, Citation1973; Duncan et al., Citation1974) supports Cole's (Citation1946) original findings that many apparently normal horses have changes in the histological structure of intrinsic laryngeal muscles, such as would be expected from a progressive, unilateral denervation atrophy. In this study, equine larynges have been collected and examined to determine the presence of contralateral weight differences in those muscles.
