Clinical significance
Diverticulosis
Spaces between the circular bands of taeniae are weak points in the bowel, and are the sites of diverticulosis. Most diverticulosis occur in the sigmoid colon as it is the segment with the highest intraluminal pressure. Diverticulosis does not occur in the rectum as the tenia coli become a continuous muscular layer. Diverticulosis can then become diverticulitis if the patient develops inflammation of the diverticulosis, this whole spectrum of disease is called diverticular disease.
Surgical landmark
The taeniae coli are important anatomical landmarks often used by surgeons performing an appendectomy to localize the appendix. By following the bands inferiorly along the ascending colon and cecum, the surgeon is able to identify the base of the appendix.[2]

Destruction of the sacral spinal cord will eliminate parasympathetic outflow to the hindgut, pelvic organs, and perineum as well as somatic innervation to much of the pelvis and lower limbs. Because it stimulates gut motility and tone, loss of parasympathetic input will result in relaxation and inactivity of the teniæ coli in the descending colon.
