Anatomical studies on the ear muscles of the Korean native goat

한국재래산양의 이개근에 대한 해부학적 연구

This study was carried out to investigate the origin, insertion, direction of muscle fibers and structure of the ear muscles of the Korean native goat. The description was based on the dissection of fifteen the Korean native goats with embalming fluid. The results were as follows: 1. The ear muscles of the Korean native goat were composed of the M. zygomaticoauricularis, M. scutuloauricularis superficialis, M. scutuloauricularis profundus, M. frontoscutularis, M. interscutularis, M. parietoauricularis, M. cervicoscutularis, M. cervicoauricularis superficialis, M. cervicoauricularis medius, M. cervicoauricularis profundus, M. auricularis profundus posterior and M. parotidoauricularis. 2. The M. frontoscutularis clearly seperated into temporal and frontal parts in 6 cases. 3. The M. scutuloauricularis profundus clearly separated into major and minor parts. 4. The M. zygomaticoauricularis blended with the M. parotidoauricularis near its insertion, but not with the M. scutuloauricularis.
