Fig. 1From: Coelomocytes of the Oligochaeta earthworm Lumbricus terrestris (Linnaeus, 1758) as evolutionary key of defense: a morphological studyCross Sects. (5 µm thick) of Lumbricus terrestris, 20x and 40x. These sections were stained with Mallory Trichrome and AB/PAS demonstrating the architecture of the cuticle (C), the epidermis (Ep), longitudinal muscle (LM), and circular muscle (CM). The epidermis is morphologically well-defined; it is either a single epithelial layer or pseudostratified; it consists of supporting epithelial cells (arrowheads) and mucous glandular cells (arrows)Back to article page
