Final answer:
The strips of longitudinal muscle fibers in the colon are called tenia coli. Tonic contractions of the tenia coli bunch up the colon into a succession of pouches called haustra, which are responsible for the wrinkled appearance of the colon. Attached to the teniae coli are small, fat-filled sacs of visceral peritoneum called epiploic appendages.
Step-by-step explanation:
The strips of longitudinal muscle fibers in the colon are called tenia coli. These are three distinct bands of smooth muscle that make up the longitudinal muscle layer of the muscularized of the large intestine, except at its terminal end.
Tonic contractions of the tenia coli bunch up the colon into a succession of pouches called haustra, which are responsible for the wrinkled appearance of the colon.
Attached to the tenia coli are small, fat-filled sacs of visceral peritoneum called epiploic appendages.
