Light microscopic examination of living giant axons from the walking legs of Hemigrapsus nudus revealed intra-axonal inclusions which were usually several tens of micrometers long and about 5 micron wide. The inclusions were filled with small light-scattering particles. The inclusions were shown, by thin section electron microscopy, to be composed largely 68% by volume) of mitochondria. Each inclusion was surrounded by membrane bounded spaces which are presumed to represent a part of the smooth endoplasmic reticulum. Similar inclusions were not found in the leg axons of a variety of other decapod crustaceans.
对裸掌盾牌蟹步足的活体巨轴突进行光学显微镜检查，发现轴突内有内含物，这些内含物通常长几十微米，宽约5微米。内含物充满了小的光散射颗粒。通过超薄切片电子显微镜观察发现，这些内含物大部分（按体积计68%）由线粒体组成。每个内含物都被膜界定的空间所包围，这些空间被认为是光滑内质网的一部分。在其他多种十足目甲壳动物的腿部轴突中未发现类似的内含物。
