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 three teniae coli: mesocolic, free and omental taeniae coli. The teniae coli contract lengthwise to produce the haustra, the bulges in the colon. The teniae coli are regulated by the sacral nerves of the spinal cord, which are under control of the parasympathetic nervous system.
