Which of the Following are Longitudinal Bands of Smooth Muscle

Question

Which of the following are longitudinal bands of smooth muscle in the large intestine?
A) muscularis mucosae
B) haustra
C) taeniae coli
D) fatty appendices

Accepted Answer

Taeniae coli are longitudinal bands of smooth muscle in the large intestine. Muscularis mucosae is a layer of smooth muscle in the digestive tract, but it is not specific to the large intestine. Haustra are sac-like structures caused by circular muscles in the large intestine. Fatty appendices are small bundles of fat attached to the large intestine, but do not contain smooth muscle.
