The taeniae coli can be seen and are responsible for the bulges (haustra) present in the colon.
At the rectosigmoid junction, the taeniae spread out and unite to form longitudinal muscle layer.
Along the sides of the taeniae, tags of peritoneum filled with fat, called epiploic appendages (or appendices epiploicae) are found.
The wall has an outer layer of longitudinal muscles, the taeniae coli, and an inner layer of circular muscles.
However, the taeniae coli and accompanying haustra are not found in either carnivorans or ruminants.
The outer longitudinal layer of the colon thins out into 3 discontinuous longitudinal bands, known as taeniae coli (bands of the colon).
