Earthworm (Cross Section)
Lumbricus terrestris
A cross section (C.S.) of an earthworm showcasing typical coelamate annelid structural organization. The outer wall features a thin cuticle lining an epidermal layer, followed by well-developed circular muscle and thick longitudinal muscle bands organized in feather-like bundles. The central coelomic cavity surrounds an intestinal tract with a distinct dorsal typhlosole fold and outer chloragogen cell layer, alongside major longitudinal blood vessels and ventral nerve cord components.
