Taenia coli



The teniae coli (also taeniae coli) are three separate longitudinal ribbons of smooth muscle on the outside of the ascending, transverse, descending and sigmoid colons. They are visible, and can be seen just below the serosa or fibrosa. There are 3 teniae coli: Mesocolic, Free and Omental Coli taenia . The teniae coli contract lengthwise to produce the haustra, the bulges in the colon.
