The origin of the styloglossus muscle was histologically studied bilaterally in nine human fetuses (18 sides). In all cases, the muscle originated in Reichert's cartilage, which gives rise to the temporal styloid process. We identified three types of variation: type A, an accessory muscle fascicle originating from the mandibular angle, found in 7 cases (12 sides); type B, where the styloglossus muscle was attached to the mandibular angle by fibrous tracts, found in three cases (4 sides); and type C, where an accessory muscle fascicle arose from the fibrous tract connecting Reichert's cartilage to the mandibular angle; found in one case. In all cases (2 sides), the styloglossus muscle was innervated by the hypoglossal nerve. Relationships between the styloglossus muscle and vasculonervous elements of the prestyloid and retrostyloid spaces were analysed.
对9例人类胎儿（18侧）的茎突舌肌起点进行了双侧组织学研究。在所有病例中，该肌肉起自形成颞茎突的 Reichert软骨。我们识别出三种变异类型：A型，7例（12侧）发现有起自下颌角的副肌束；B型，3例（4侧）发现茎突舌肌通过纤维束附着于下颌角；C型，1例发现有起自连接Reichert软骨与下颌角的纤维束的副肌束。在所有病例（2侧）中，茎突舌肌由舌下神经支配。分析了茎突舌肌与茎突前间隙和茎突后间隙血管神经结构的关系。
