No, mucus is not a muscle but a secretion in epithelial tissue.

There is no skeletal muscle that is covered with a mucous membrane. Skeletal muscles are typically covered with connective tissue known as the epimysium, perimysium, and endomysium, which provide protection and support for the muscle fibers. Mucous membranes are typically found lining organs in the respiratory, digestive, and urinary systems to provide protection and help with absorption.
An ulcer is not a type of muscle. It is an open sore on a mucous membrane like the stomach wall or on the skin.
