FIGURE 21.15 | Uterine Tube: Mucosal Folds

A higher magnification of the mucosal fold epithelium shows the ciliated cells
(3) and nonciliated peg (secretory) cells (1). The ciliated cells (3) are most
numerous in the infundibulum and ampulla of the uterine tube. The beat of the
cilia is directed toward the uterus. Inferior to the epithelium is the basement

membrane (2) and lamina propria (4) with blood vessels (5) and loose
connective tissue. During the early proliferative phase of the menstrual cycle and
under the influence of estrogen, the ciliated cells (3) undergo hypertrophy,
exhibit cilia growth, and become predominant. In addition, the nonciliated peg

cells (1) increase their secretory activity. The epithelium of the uterine tube
shows cyclic changes, with the proportion of ciliated and nonciliated cells
varying in the stages of the menstrual cycle.
