In the core of the mucosal fold is the highly cellular connective tissue
(CT) and the blood vessels (BV) within the connective tissue. The
lumen of the tube is lined by a simple columnar epithelium
composed of ciliated cells (arrow) and nonciliated cells. The
connective tissue contains cells whose nuclei are arranged typically
in a random manner. They vary in shape, being elongated, oval, or
round. The character of the connective tissue is essentially the same
from the epithelium to the muscularis, and for this reason, no
submucosa is described.
