Taenia coli

Anatomy

3 distinct, separated, equally spaced, longitudinal ribbons/straps of muscle (mesocolic, free, omental) along the length of ascending, transverse, descending and sigmoid colon, visible just below serosa, shorter than other corresponding colonic layers, thus puckering the colon between them (even more on contraction), and giving rise to haustra/sacculations; converge at either end – rectum, base appendix.
