The attachments, course, and interrelationships of M. genioglossus were examined in 28 fifteen-week human fetal specimens. Observations were made from histologic sections of the tongue cut in one of the three standard planes of section. The anterior-most genioglossal fibers insert near the tip of the tongue at the level of the anterior extent of the median septum. Within the central mass of the tongue, some fibers of this muscle characteristically decussate across midline, a limited number below the level of the septum and a considerably larger number above it. Posteriorly, a few of the most posterior and inferior fibers of M. genioglossus could be traced to an attachment on the thickened perichondrium on the superior edge of the hyoid anlage. In other respects, the disposition of genioglossal fibers at this stage of development resembles closely that description generally given for the adult structure.
在28个15周大的人类胎儿标本中，对颏舌肌的附着、走行及其相互关系进行了研究。观察是通过在三个标准切片平面之一中切割的舌组织切片进行的。最前方的颏舌肌纤维在舌尖附近、正中隔前方延伸水平处附着。在舌的中央部分，该肌肉的一些纤维特征性地在中线交叉，在隔水平以下数量有限，在隔水平以上数量较多。在后方，颏舌肌最靠后和最靠下的一些纤维可追踪至舌骨原基上缘增厚的骨膜附着处。在其他方面，在这个发育阶段颏舌肌纤维的分布与通常对成人结构的描述非常相似。
