The relations between the saccus lacrimalis and different portions of the musculus orbicularis oculi were studied in orbital regions of human fetuses sectioned into numbered series. No insertions of the pars lacrimalis or Horner's muscle on the saccus were found. These muscular fibres pass along the dorsal wall of the saccus and are separated from it by the reflex tendon of the ligamentum palpebrale mediale. The only muscular fibres that insert on the saccus are those that approach the anterior face of the saccus and the fornix. The fibres that insert on the anterior face proceed from the deep bundles of the pars preseptalis of the lower eyelids, and those that insert on the fornix derive from the deep bundles of the pars preseptalis of the upper eyelid.
在对连续编号切片的人类胎儿眼眶区域进行研究时，观察了泪囊与眼轮匝肌不同部分之间的关系。未发现泪囊部或霍纳肌在泪囊上的附着。这些肌纤维沿泪囊后壁走行，并被内侧睑韧带的反折腱膜与泪囊分隔。唯一附着于泪囊的肌纤维是那些靠近泪囊前表面和穹窿的纤维。附着于泪囊前表面的纤维来自下睑眶隔前部的深层束，而附着于穹窿的纤维则来自上睑眶隔前部的深层束。
