superior fallopian tube epithelium

The superior fallopian tube epithelium is the region of the tubal lining located on the uppermost surface of the fallopian tube. It is a positional subdivision of the simple columnar epithelium forming the inner lining of the fallopian tube and is continuous with the inferior, mesosalpinx-proximal, and antimesosalpinx-proximal epithelial regions.

The superior fallopian tube epithelium is located along the top surface of the fallopian tube as it courses within the broad ligament. It faces upward toward the peritoneal cavity and is part of the mucosa of the entire length of the tube from its uterine opening to the fimbriated end.

The superior tubal epithelium participates in ovum and sperm transport through ciliary beating directed toward the uterus, and through secretion of tubal fluid that creates a conducive environment for fertilization. Regional differences in ciliary density and secretory activity may exist across the tubal circumference.

The superior fallopian tube epithelium may be affected by infectious salpingitis, endometriosis implants on the tubal surface, and ectopic pregnancy. Chronic inflammation may be associated with loss of ciliated cells and epithelial damage that impairs normal reproductive function.

Examination of the superior fallopian tube epithelium is performed on histological sections of fallopian tube tissue. Cross-sectional and longitudinal sections allow comparison of epithelial morphology at different positions around the tubal circumference, and special stains may be applied to identify specific cell populations.
