Electron microscopical studies reveal that the phasmids of Scutellonema brachyurum include socket and sheath cells which appear to be secretory. The phasmid includes an external cup-shaped ampulla filled with electron-dense material which may be lipopolysaccharide. The ampulla is continuous, with a receptor cavity surrounded by the socket and sheath cells. The dendrite receptor originates from a neuron and directs posteriorly through a receptor socket into the receptor cavity ending near the electron-dense plug. Serial sections through the dendrite receptor indicate that it does not conform to the typical 9+2 arrangement of microtubules characteristic of cilia in higher animals.
电子显微镜研究表明，短尾盾线虫的侧尾腺包括似乎具有分泌功能的套接细胞和鞘细胞。侧尾腺包括一个外部杯状壶腹，其充满了可能是脂多糖的电子致密物质。壶腹是连续的，有一个被套接细胞和鞘细胞包围的感受器腔。树突状感受器起源于一个神经元，向后穿过感受器套接进入感受器腔，在电子致密栓附近终止。对树突状感受器的连续切片表明，它不符合高等动物中典型的纤毛的9+2微管排列。
