A roundworm cross section shows the inside of Ascaris as a round relief slice, ready to study from the front. The tough outer cuticle rings the edge, a thick band of muscle cells fans inward with finger-like arms, and the flattened intestine sits at the centre with its lined wall. Lateral cords divide the muscle field on each side. The wavy, realistic texture makes every layer easy to point out in a biology classroom or lab display.
