1.蜕皮期多刺龙虾（C期晚期）鳃区的外皮组织由外珠被和内珠被界定。外珠被由四层组成：薄的上表皮、色素层、主层和膜层。上表皮和色素层都是在蜕皮前形成的。内珠被厚度约为外珠被的1/20，由两层组成，一层非常薄的上表皮和一层染色均匀的内表皮.珠被组织由柱状表皮细胞和疏松海绵状的表皮下结缔组织组成。大的卵圆形储备细胞构成了该组织中最主要的细胞类型。这些细胞在整个蜕皮周期的各个阶段储存大量的碳水化合物，脂质和钙;它们也存在于肝胰腺中。在肝胰腺的管状上皮内有两种主要类型的细胞，分泌细胞和吸收细胞。前者是swol.
1. The integumental tissues from the branchial region of an intermolt spiny lobster (late Stage C) are bordered by an outer and an inner integument. The outer integument consists of four layers: a thin epicuticle, the pigmented layer, the principal layer, and the membranous layer. Both the epicuticle and pigmented layer are formed before molt. The inner integument, about 1/20 the thickness of the outer integument, is composed of two layers, a very thin epicuticle and a uniformly staining endocuticle.2. The integumental tissues are composed of columnar epidermal cells and a sub-epidermal connective tissue of a loose spongy type. Large oval reserve cells constitute by far the most predominant type of cells in this tissue. These cells store abundant amounts of carbohydrate, lipid and calcium at various stages throughout the molting cycle; they are also found in the hepatopancreas.3. Within the tubular epithelium of the hepatopancreas are two major types of cells, secretory and absorptive. The former are swol...
