The ultrastructure of the formation of the first-stage cuticle within the egg of Trichostrongylus colubriformis is described. The first indication of cuticle formation was the formation of the epicuticle external to the epidermal plasma membrane. This becomes thickened to form the epicuticle of the fully formed cuticle. Microtubules and microfilaments associated with the epidermal plasma membrane were observed during the early phases of cuticle formation. The basal zone was secreted into the space between the epicuticle and the epidermal plasma membrane, followed by the formation of the cortical zone. The basal zone had a striated appearance during the earliest stages of its formation.
描述了蛇形毛圆线虫卵内第一期角质层形成的超微结构。角质层形成的最初迹象是在表皮质膜外部形成表皮层。它会增厚形成完全形成的角质层的表皮层。在角质层形成的早期阶段观察到与表皮质膜相关的微管和微丝。基部区域分泌到表皮层和表皮质膜之间的空间中，随后形成皮质区域。基部区域在其形成的最早阶段具有条纹状外观。
