光镜和电镜观察表明，口腔腺细胞有两个明显不同的区带。在内侧，基底区与体液和内柱接触。其强烈的亲派若宁细胞质含有极指状核和许多小线粒体。横向上，顶区与表皮接触，它也可以在表皮细胞之间发送突起，并将细胞碎片运送到新房子的原基中。这个细胞带包含许多细胞膜。口腔腺细胞可能是发光腺。结合到房屋墙壁中的富含膜的细胞碎片可能是空房子中报道的生物发光的来源。个体发育相关的索下细胞具有类似的结构，这些细胞也可能是光生产者。
Light microscopic and EM studies showed that the oral gland cells have 2 quite different zones. Medially, the basal zone is in contact with body fluids and the endostyle. Its strongly pyroninophile cytoplasm contains the extremely digitated nucleus and numerous small mitochondria. Laterally, the apical zone contacts the epidermis and it may also send a process between epidermal cells and deliver cell fragments into the primordium of the new house. This cell zone contains numerous membranes. The oral gland cells are probably light producing glands. The membrane-rich cell fragments which are incorporated into the house wall may be the source of the bioluminescence which has been reported from empty houses. The ontogenetically related subchordal cells have a similar structure and it is possible that these cells are also light producers.
