The body wall fine structure including the cuticle, hypodermis, and somatic muscles is similar in males of Meloidogyne incognita and Heterodera glycines. The cuticle can be regarded as basically three-layered in both species, but is much thicker in M. incognita than in H. glycines, and differences occur in surface markings. The chordal and interchordal hypodermis is syncytial. Hypodermal tissue pervades the lip region, and lines the stomatal cavity and stylet shaft. Various organelles and structures, some previously undescribed, are concentrated in the chords. Their possible role in lipid metabolism is considered, as well as the probable function of the hypodermis in fornlation of the cephalic framework and stylet. The interchordal hypodermis which encloses peripheral nerves, is periodically transversed by bundles of fibrils which are homologous with the subcuticular striation previously observed in the light microscope. The somatic musculature is meromyarian, and the muscle cells are of the platymyarian type with I, A, and H bands, but without Z bands or T tubules. Thin dense bands are present in the H bands, and appear to be associated with sarcoplasmic reticulum.
南方根结线虫和大豆胞囊线虫雄性个体的体壁精细结构，包括角质层、皮下组织和体壁肌肉，是相似的。在这两个物种中，角质层基本上都可视为三层结构，但南方根结线虫的角质层比大豆胞囊线虫的厚得多，且表面斑纹存在差异。弦状和弦间皮下组织是多核的。皮下组织遍布唇部区域，并衬于气孔腔和口针杆。各种细胞器和结构，有些以前未曾描述过，集中在弦中。文中考虑了它们在脂质代谢中的可能作用，以及皮下组织在头部框架和口针形成中的可能功能。包围外周神经的弦间皮下组织，会被与先前在光学显微镜下观察到的皮下横纹同源的纤维束周期性横穿。体壁肌肉是分节肌，肌肉细胞为扁肌型，有I、A和H带，但没有Z带或T小管。H带中有细的致密带，似乎与肌浆网有关。
