Final Answer:
The colon walls are made up of axial strips of muscle called the taeniae coli and outpouches of the wall called haustra.
Step-by-step explanation:
The colon, also known as the large intestine, exhibits distinctive features in its muscular structure. The axial strips of longitudinal muscle running along the length of the colon are called taeniae coli. These taeniae coli create a segmented appearance on the colon's surface. The circular muscle layer of the colon contracts to form pouches or outpouches, and these are called haustra.
Haustra give the colon its characteristic sacculated appearance. The combined action of the taeniae coli and haustra contributes to the unique motility and function of the colon, facilitating the movement of fecal material through the organ in a coordinated manner.
