What the illustration shows
English anatomy poster on navy titled “What Are the Bands and Pouches on Your Colon?” A peach colon segment has a visible longitudinal band labeled Teniae coli and pouch-like contours labeled Haustra. The open end is labeled Colon wall. An end-on section below marks exactly three outer muscle thickenings around one central lumen. A lower-right colon locator ends in a smooth rectum with text saying it lacks teniae and haustra. Gold AllHumanBody.com and the full slogan appear at the bottom.
How to interpret this poster
- Normal contour identification, not diverticula, sealed compartments or a fixed contraction schedule. Wall thickness and mucosal folds are illustrative.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
